/**
*
* A MessageFormat produces concatenated messages in a
* language-neutral way. It should be used for all string
* concatenations that are visible to end users.
* <P>
* A MessageFormat contains an array of <EM>subformats</EM> arranged
* within a <EM>template string</EM>. Together, the subformats and
* template string determine how the MessageFormat will operate during
* formatting and parsing.
* <P>
* Typically, both the subformats and the template string are
* specified at once in a <EM>pattern</EM>. By using different
* patterns for different locales, messages may be localized.
* <P>
* During formatting, the MessageFormat takes an array of arguments
* and produces a user-readable string. Each argument is a
* Formattable object; they may be passed in in an array, or as a
* single Formattable object which itself contains an array. Each
* argument is matched up with its corresponding subformat, which then
* formats it into a string. The resultant strings are then assembled
* within the string template of the MessageFormat to produce the
* final output string.
* <P>
* During parsing, an input string is matched against the string
* template of the MessageFormat to produce an array of Formattable
* objects. Plain text of the template string is matched directly
* against intput text. At each position in the template string where
* a subformat is located, the subformat is called to parse the
* corresponding segment of input text to produce an output argument.
* In this way, an array of arguments is created which together
* constitute the parse result.
* <P>
* Parsing may fail or produce unexpected results in a number of
* circumstances.
* <UL>
* <LI>If one of the arguments does not occur in the pattern, it
* will be returned as a default Formattable.
* <LI>If the format of an argument is loses information, such as with
* a choice format where a large number formats to "many", then the
* parse may not correspond to the originally formatted argument.
* <LI>MessageFormat does not handle ChoiceFormat recursion during
* parsing; such parses will fail.
* <LI>Parsing will not always find a match (or the correct match) if
* some part of the parse is ambiguous. For example, if the pattern
* "{1},{2}" is used with the string arguments {"a,b", "c"}, it will
* format as "a,b,c". When the result is parsed, it will return {"a",
* "b,c"}.
* <LI>If a single argument is formatted more than once in the string,
* then the rightmost subformat in the pattern string will produce the
* parse result; prior subformats with the same argument index will
* have no effect.
* </UL>
* Here are some examples of usage:
* <P>
* Example 1:
* <pre>
* \code
* UErrorCode success = U_ZERO_ERROR;
* GregorianCalendar cal(success);
* Formattable arguments[] = {
* 7L,
* Formattable( (Date) cal.getTime(success), Formattable::kIsDate),
* "a disturbance in the Force"
* };
*
* UnicodeString result;
* MessageFormat::format(
* "At {1,time} on {1,date}, there was {2} on planet {0,number}.",
* arguments, 3, result, success );
*
* cout << "result: " << result << endl;
* //<output>: At 4:34:20 PM on 23-Mar-98, there was a disturbance
* // in the Force on planet 7.
* \endcode
* </pre>
* Typically, the message format will come from resources, and the
* arguments will be dynamically set at runtime.
* <P>
* Example 2:
* <pre>
* \code
* success = U_ZERO_ERROR;
* Formattable testArgs[] = {3L, "MyDisk"};
*
* MessageFormat form(
* "The disk \"{1}\" contains {0} file(s).", success );
*
* UnicodeString string;
* FieldPosition fpos = 0;
* cout << "format: " << form.format(testArgs, 2, string, fpos, success ) << endl;
*
* // output, with different testArgs:
* // output: The disk "MyDisk" contains 0 file(s).
* // output: The disk "MyDisk" contains 1 file(s).
* // output: The disk "MyDisk" contains 1,273 file(s).
* \endcode
* </pre>
*
* The pattern is of the following form. Legend:
* <pre>
* \code
* {optional item}
* (group that may be repeated)*
* \endcode
* </pre>
* Do not confuse optional items with items inside quotes braces, such
* as this: "{". Quoted braces are literals.
* <pre>
* \code
* messageFormatPattern := string ( "{" messageFormatElement "}" string )*
*
* messageFormatElement := argumentIndex { "," elementFormat }
*
* elementFormat := "time" { "," datetimeStyle }
* | "date" { "," datetimeStyle }
* | "number" { "," numberStyle }
* | "choice" "," choiceStyle
*
* datetimeStyle := "short"
* | "medium"
* | "long"
* | "full"
* | dateFormatPattern
*
* numberStyle := "currency"
* | "percent"
* | "integer"
* | numberFormatPattern
*
* choiceStyle := choiceFormatPattern
* \endcode
* </pre>
* If there is no elementFormat, then the argument must be a string,
* which is substituted. If there is no dateTimeStyle or numberStyle,
* then the default format is used (e.g. NumberFormat::createInstance(),
* DateFormat::createTimeInstance(DateFormat::kDefault, ...) or DateFormat::createDateInstance(DateFormat::kDefault, ...). For
* a ChoiceFormat, the pattern must always be specified, since there
* is no default.
* <P>
* In strings, single quotes can be used to quote syntax characters.
* A literal single quote is represented by '', both within and outside
* of single-quoted segments. Inside a
* messageFormatElement, quotes are <EM>not</EM> removed. For example,
* {1,number,$'#',##} will produce a number format with the pound-sign
* quoted, with a result such as: "$#31,45".
* <P>
* If a pattern is used, then unquoted braces in the pattern, if any,
* must match: that is, "ab {0} de" and "ab '}' de" are ok, but "ab
* {0'}' de" and "ab } de" are not.
* <p>
* <dl><dt><b>Warning:</b><dd>The rules for using quotes within message
* format patterns unfortunately have shown to be somewhat confusing.
* In particular, it isn't always obvious to localizers whether single
* quotes need to be doubled or not. Make sure to inform localizers about
* the rules, and tell them (for example, by using comments in resource
* bundle source files) which strings will be processed by MessageFormat.
* Note that localizers may need to use single quotes in translated
* strings where the original version doesn't have them.
* <br>Note also that the simplest way to avoid the problem is to
* use the real apostrophe (single quote) character U+2019 (') for
* human-readable text, and to use the ASCII apostrophe (U+0027 ' )
* only in program syntax, like quoting in MessageFormat.
* See the annotations for U+0027 Apostrophe in The Unicode Standard.</p>
* </dl>
* <P>
* The argumentIndex is a non-negative integer, which corresponds to the
* index of the arguments presented in an array to be formatted. The
* first argument has argumentIndex 0.
* <P>
* It is acceptable to have unused arguments in the array. With missing
* arguments or arguments that are not of the right class for the
* specified format, a failing UErrorCode result is set.
* <P>
* For more sophisticated patterns, you can use a ChoiceFormat to get
* output:
* <pre>
* \code
* UErrorCode success = U_ZERO_ERROR;
* MessageFormat* form("The disk \"{1}\" contains {0}.", success);
* double filelimits[] = {0,1,2};
* UnicodeString filepart[] = {"no files","one file","{0,number} files"};
* ChoiceFormat* fileform = new ChoiceFormat(filelimits, filepart, 3);
* form.setFormat(1, *fileform); // NOT zero, see below
*
* Formattable testArgs[] = {1273L, "MyDisk"};
*
* UnicodeString string;
* FieldPosition fpos = 0;
* cout << form.format(testArgs, 2, string, fpos, success) << endl;
*
* // output, with different testArgs
* // output: The disk "MyDisk" contains no files.
* // output: The disk "MyDisk" contains one file.
* // output: The disk "MyDisk" contains 1,273 files.
* \endcode
* </pre>
* You can either do this programmatically, as in the above example,
* or by using a pattern (see ChoiceFormat for more information) as in:
* <pre>
* \code
* form.applyPattern(
* "There {0,choice,0#are no files|1#is one file|1<are {0,number,integer} files}.");
* \endcode
* </pre>
* <P>
* <EM>Note:</EM> As we see above, the string produced by a ChoiceFormat in
* MessageFormat is treated specially; occurences of '{' are used to
* indicated subformats, and cause recursion. If you create both a
* MessageFormat and ChoiceFormat programmatically (instead of using
* the string patterns), then be careful not to produce a format that
* recurses on itself, which will cause an infinite loop.
* <P>
* <EM>Note:</EM> Subformats are numbered by their order in the pattern.
* This is <EM>not</EM> the same as the argumentIndex.
* <pre>
* \code
* For example: with "abc{2}def{3}ghi{0}...",
*
* format0 affects the first variable {2}
* format1 affects the second variable {3}
* format2 affects the second variable {0}
* \endcode
* </pre>
*
* <p><em>User subclasses are not supported.</em> While clients may write
* subclasses, such code will not necessarily work and will not be
* guaranteed to work stably from release to release.
