+/**
+ * PrintfFormat allows the formatting of an array of
+ * objects embedded within a string. Primitive types
+ * must be passed using wrapper types. The formatting
+ * is controlled by a control string.
+ *<p>
+ * A control string is a Java string that contains a
+ * control specification. The control specification
+ * starts at the first percent sign (%) in the string,
+ * provided that this percent sign
+ *<ol>
+ *<li>is not escaped protected by a matching % or is
+ * not an escape % character,
+ *<li>is not at the end of the format string, and
+ *<li>precedes a sequence of characters that parses as
+ * a valid control specification.
+ *</ol>
+ *</p><p>
+ * A control specification usually takes the form:
+ *<pre> % ['-+ #0]* [0..9]* { . [0..9]* }+
+ * { [hlL] }+ [idfgGoxXeEcs]
+ *</pre>
+ * There are variants of this basic form that are
+ * discussed below.</p>
+ *<p>
+ * The format is composed of zero or more directives
+ * defined as follows:
+ *<ul>
+ *<li>ordinary characters, which are simply copied to
+ * the output stream;
+ *<li>escape sequences, which represent non-graphic
+ * characters; and
+ *<li>conversion specifications, each of which
+ * results in the fetching of zero or more arguments.
+ *</ul></p>
+ *<p>
+ * The results are undefined if there are insufficient
+ * arguments for the format. Usually an unchecked
+ * exception will be thrown. If the format is
+ * exhausted while arguments remain, the excess
+ * arguments are evaluated but are otherwise ignored.
+ * In format strings containing the % form of
+ * conversion specifications, each argument in the
+ * argument list is used exactly once.</p>
+ * <p>
+ * Conversions can be applied to the <code>n</code>th
+ * argument after the format in the argument list,
+ * rather than to the next unused argument. In this
+ * case, the conversion characer % is replaced by the
+ * sequence %<code>n</code>$, where <code>n</code> is
+ * a decimal integer giving the position of the
+ * argument in the argument list.</p>
+ * <p>
+ * In format strings containing the %<code>n</code>$
+ * form of conversion specifications, each argument
+ * in the argument list is used exactly once.</p>
+ *
+ *<h4>Escape Sequences</h4>
+ *<p>
+ * The following table lists escape sequences and
+ * associated actions on display devices capable of
+ * the action.
+ *<table>
+ *<tr><th align=left>Sequence</th>
+ * <th align=left>Name</th>
+ * <th align=left>Description</th></tr>
+ *<tr><td>\\</td><td>backlash</td><td>None.
+ *</td></tr>
+ *<tr><td>\a</td><td>alert</td><td>Attempts to alert
+ * the user through audible or visible
+ * notification.
+ *</td></tr>
+ *<tr><td>\b</td><td>backspace</td><td>Moves the
+ * printing position to one column before
+ * the current position, unless the
+ * current position is the start of a line.
+ *</td></tr>
+ *<tr><td>\f</td><td>form-feed</td><td>Moves the
+ * printing position to the initial
+ * printing position of the next logical
+ * page.
+ *</td></tr>
+ *<tr><td>\n</td><td>newline</td><td>Moves the
+ * printing position to the start of the
+ * next line.
+ *</td></tr>
+ *<tr><td>\r</td><td>carriage-return</td><td>Moves
+ * the printing position to the start of
+ * the current line.
+ *</td></tr>
+ *<tr><td>\t</td><td>tab</td><td>Moves the printing
+ * position to the next implementation-
+ * defined horizontal tab position.
+ *</td></tr>
+ *<tr><td>\v</td><td>vertical-tab</td><td>Moves the
+ * printing position to the start of the
+ * next implementation-defined vertical
+ * tab position.
+ *</td></tr>
+ *</table></p>
+ *<h4>Conversion Specifications</h4>
+ *<p>
+ * Each conversion specification is introduced by
+ * the percent sign character (%). After the character
+ * %, the following appear in sequence:</p>
+ *<p>
+ * Zero or more flags (in any order), which modify the
+ * meaning of the conversion specification.</p>
+ *<p>
+ * An optional minimum field width. If the converted
+ * value has fewer characters than the field width, it
+ * will be padded with spaces by default on the left;
+ * t will be padded on the right, if the left-
+ * adjustment flag (-), described below, is given to
+ * the field width. The field width takes the form
+ * of a decimal integer. If the conversion character
+ * is s, the field width is the the minimum number of
+ * characters to be printed.</p>
+ *<p>
+ * An optional precision that gives the minumum number
+ * of digits to appear for the d, i, o, x or X
+ * conversions (the field is padded with leading
+ * zeros); the number of digits to appear after the
+ * radix character for the e, E, and f conversions,
+ * the maximum number of significant digits for the g
+ * and G conversions; or the maximum number of
+ * characters to be written from a string is s and S
+ * conversions. The precision takes the form of an
+ * optional decimal digit string, where a null digit
+ * string is treated as 0. If a precision appears
+ * with a c conversion character the precision is
+ * ignored.
+ * </p>
+ *<p>
+ * An optional h specifies that a following d, i, o,
+ * x, or X conversion character applies to a type
+ * short argument (the argument will be promoted
+ * according to the integral promotions and its value
+ * converted to type short before printing).</p>
+ *<p>
+ * An optional l (ell) specifies that a following
+ * d, i, o, x, or X conversion character applies to a
+ * type long argument.</p>
+ *<p>
+ * A field width or precision may be indicated by an
+ * asterisk (*) instead of a digit string. In this
+ * case, an integer argument supplised the field width
+ * precision. The argument that is actually converted
+ * is not fetched until the conversion letter is seen,
+ * so the the arguments specifying field width or
+ * precision must appear before the argument (if any)
+ * to be converted. If the precision argument is
+ * negative, it will be changed to zero. A negative
+ * field width argument is taken as a - flag, followed
+ * by a positive field width.</p>
+ * <p>
+ * In format strings containing the %<code>n</code>$
+ * form of a conversion specification, a field width
+ * or precision may be indicated by the sequence
+ * *<code>m</code>$, where m is a decimal integer
+ * giving the position in the argument list (after the
+ * format argument) of an integer argument containing
+ * the field width or precision.</p>
+ * <p>
+ * The format can contain either numbered argument
+ * specifications (that is, %<code>n</code>$ and
+ * *<code>m</code>$), or unnumbered argument
+ * specifications (that is % and *), but normally not
+ * both. The only exception to this is that %% can
+ * be mixed with the %<code>n</code>$ form. The
+ * results of mixing numbered and unnumbered argument
+ * specifications in a format string are undefined.</p>
+ *
+ *<h4>Flag Characters</h4>
+ *<p>
+ * The flags and their meanings are:</p>
+ *<dl>
+ * <dt>'<dd> integer portion of the result of a
+ * decimal conversion (%i, %d, %f, %g, or %G) will
+ * be formatted with thousands' grouping
+ * characters. For other conversions the flag
+ * is ignored. The non-monetary grouping
+ * character is used.
+ * <dt>-<dd> result of the conversion is left-justified
+ * within the field. (It will be right-justified
+ * if this flag is not specified).</td></tr>
+ * <dt>+<dd> result of a signed conversion always
+ * begins with a sign (+ or -). (It will begin
+ * with a sign only when a negative value is
+ * converted if this flag is not specified.)
+ * <dt><space><dd> If the first character of a
+ * signed conversion is not a sign, a space
+ * character will be placed before the result.
+ * This means that if the space character and +
+ * flags both appear, the space flag will be
+ * ignored.
+ * <dt>#<dd> value is to be converted to an alternative
+ * form. For c, d, i, and s conversions, the flag
+ * has no effect. For o conversion, it increases
+ * the precision to force the first digit of the
+ * result to be a zero. For x or X conversion, a
+ * non-zero result has 0x or 0X prefixed to it,
+ * respectively. For e, E, f, g, and G
+ * conversions, the result always contains a radix
+ * character, even if no digits follow the radix
+ * character (normally, a decimal point appears in
+ * the result of these conversions only if a digit
+ * follows it). For g and G conversions, trailing
+ * zeros will not be removed from the result as
+ * they normally are.
+ * <dt>0<dd> d, i, o, x, X, e, E, f, g, and G
+ * conversions, leading zeros (following any
+ * indication of sign or base) are used to pad to
+ * the field width; no space padding is
+ * performed. If the 0 and - flags both appear,
+ * the 0 flag is ignored. For d, i, o, x, and X
+ * conversions, if a precision is specified, the
+ * 0 flag will be ignored. For c conversions,
+ * the flag is ignored.
+ *</dl>
+ *
+ *<h4>Conversion Characters</h4>
+ *<p>
+ * Each conversion character results in fetching zero
+ * or more arguments. The results are undefined if
+ * there are insufficient arguments for the format.
+ * Usually, an unchecked exception will be thrown.
+ * If the format is exhausted while arguments remain,
+ * the excess arguments are ignored.</p>
+ *
+ *<p>
+ * The conversion characters and their meanings are:
+ *</p>
+ *<dl>
+ * <dt>d,i<dd>The int argument is converted to a
+ * signed decimal in the style [-]dddd. The
+ * precision specifies the minimum number of
+ * digits to appear; if the value being
+ * converted can be represented in fewer
+ * digits, it will be expanded with leading
+ * zeros. The default precision is 1. The
+ * result of converting 0 with an explicit
+ * precision of 0 is no characters.
+ * <dt>o<dd> The int argument is converted to unsigned
+ * octal format in the style ddddd. The
+ * precision specifies the minimum number of
+ * digits to appear; if the value being
+ * converted can be represented in fewer
+ * digits, it will be expanded with leading
+ * zeros. The default precision is 1. The
+ * result of converting 0 with an explicit
+ * precision of 0 is no characters.
+ * <dt>x<dd> The int argument is converted to unsigned
+ * hexadecimal format in the style dddd; the
+ * letters abcdef are used. The precision
+ * specifies the minimum numberof digits to
+ * appear; if the value being converted can be
+ * represented in fewer digits, it will be
+ * expanded with leading zeros. The default
+ * precision is 1. The result of converting 0
+ * with an explicit precision of 0 is no
+ * characters.
+ * <dt>X<dd> Behaves the same as the x conversion
+ * character except that letters ABCDEF are
+ * used instead of abcdef.
+ * <dt>f<dd> The floating point number argument is
+ * written in decimal notation in the style
+ * [-]ddd.ddd, where the number of digits after
+ * the radix character (shown here as a decimal
+ * point) is equal to the precision
+ * specification. A Locale is used to determine
+ * the radix character to use in this format.
+ * If the precision is omitted from the
+ * argument, six digits are written after the
+ * radix character; if the precision is
+ * explicitly 0 and the # flag is not specified,
+ * no radix character appears. If a radix
+ * character appears, at least 1 digit appears
+ * before it. The value is rounded to the
+ * appropriate number of digits.
+ * <dt>e,E<dd>The floating point number argument is
+ * written in the style [-]d.ddde{+-}dd
+ * (the symbols {+-} indicate either a plus or
+ * minus sign), where there is one digit before
+ * the radix character (shown here as a decimal
+ * point) and the number of digits after it is
+ * equal to the precision. A Locale is used to
+ * determine the radix character to use in this
+ * format. When the precision is missing, six
+ * digits are written after the radix character;
+ * if the precision is 0 and the # flag is not
+ * specified, no radix character appears. The
+ * E conversion will produce a number with E
+ * instead of e introducing the exponent. The
+ * exponent always contains at least two digits.
+ * However, if the value to be written requires
+ * an exponent greater than two digits,
+ * additional exponent digits are written as
+ * necessary. The value is rounded to the
+ * appropriate number of digits.
+ * <dt>g,G<dd>The floating point number argument is
+ * written in style f or e (or in sytle E in the
+ * case of a G conversion character), with the
+ * precision specifying the number of
+ * significant digits. If the precision is
+ * zero, it is taken as one. The style used
+ * depends on the value converted: style e
+ * (or E) will be used only if the exponent
+ * resulting from the conversion is less than
+ * -4 or greater than or equal to the precision.
+ * Trailing zeros are removed from the result.
+ * A radix character appears only if it is
+ * followed by a digit.
+ * <dt>c,C<dd>The integer argument is converted to a
+ * char and the result is written.
+ *
+ * <dt>s,S<dd>The argument is taken to be a string and
+ * bytes from the string are written until the
+ * end of the string or the number of bytes
+ * indicated by the precision specification of
+ * the argument is reached. If the precision
+ * is omitted from the argument, it is taken to
+ * be infinite, so all characters up to the end
+ * of the string are written.
+ * <dt>%<dd>Write a % character; no argument is
+ * converted.
+ *</dl>
+ *<p>
+ * If a conversion specification does not match one of
+ * the above forms, an IllegalArgumentException is
+ * thrown and the instance of PrintfFormat is not
+ * created.</p>
+ *<p>
+ * If a floating point value is the internal
+ * representation for infinity, the output is
+ * [+]Infinity, where Infinity is either Infinity or
+ * Inf, depending on the desired output string length.
+ * Printing of the sign follows the rules described
+ * above.</p>
+ *<p>
+ * If a floating point value is the internal
+ * representation for "not-a-number," the output is
+ * [+]NaN. Printing of the sign follows the rules
+ * described above.</p>
+ *<p>
+ * In no case does a non-existent or small field width
+ * cause truncation of a field; if the result of a
+ * conversion is wider than the field width, the field
+ * is simply expanded to contain the conversion result.
+ *</p>
+ *<p>
+ * The behavior is like printf. One exception is that
+ * the minimum number of exponent digits is 3 instead
+ * of 2 for e and E formats when the optional L is used
+ * before the e, E, g, or G conversion character. The
+ * optional L does not imply conversion to a long long
+ * double. </p>
+ * <p>
+ * The biggest divergence from the C printf
+ * specification is in the use of 16 bit characters.
+ * This allows the handling of characters beyond the
+ * small ASCII character set and allows the utility to
+ * interoperate correctly with the rest of the Java
+ * runtime environment.</p>
+ *<p>
+ * Omissions from the C printf specification are
+ * numerous. All the known omissions are present
+ * because Java never uses bytes to represent
+ * characters and does not have pointers:</p>
+ *<ul>
+ * <li>%c is the same as %C.
+ * <li>%s is the same as %S.
+ * <li>u, p, and n conversion characters.
+ * <li>%ws format.
+ * <li>h modifier applied to an n conversion character.
+ * <li>l (ell) modifier applied to the c, n, or s
+ * conversion characters.
+ * <li>ll (ell ell) modifier to d, i, o, u, x, or X
+ * conversion characters.
+ * <li>ll (ell ell) modifier to an n conversion
+ * character.
+ * <li>c, C, d,i,o,u,x, and X conversion characters
+ * apply to Byte, Character, Short, Integer, Long
+ * types.
+ * <li>f, e, E, g, and G conversion characters apply
+ * to Float and Double types.
+ * <li>s and S conversion characters apply to String
+ * types.
+ * <li>All other reference types can be formatted
+ * using the s or S conversion characters only.
+ *</ul>
+ * <p>
+ * Most of this specification is quoted from the Unix
+ * man page for the sprintf utility.</p>
