/**
 * <code>FieldPosition</code> is a simple class used by <code>Format</code>
 * and its subclasses to identify fields in formatted output. Fields are
 * identified by constants, whose names typically end with <code>_FIELD</code>,
 * defined in the various subclasses of <code>Format</code>. See
 * <code>ERA_FIELD</code> and its friends in <code>DateFormat</code> for
 * an example.
 *
 * <p>
 * <code>FieldPosition</code> keeps track of the position of the
 * field within the formatted output with two indices: the index
 * of the first character of the field and the index of the last
 * character of the field.
 *
 * <p>
 * One version of the <code>format</code> method in the various
 * <code>Format</code> classes requires a <code>FieldPosition</code>
 * object as an argument. You use this <code>format</code> method
 * to perform partial formatting or to get information about the
 * formatted output (such as the position of a field).
 *
 * The FieldPosition class is not intended for public subclassing.
 *
 * <p>
 * Below is an example of using <code>FieldPosition</code> to aid
 * alignment of an array of formatted floating-point numbers on
 * their decimal points:
 * <pre>
 * \code
 *       double doubleNum[] = {123456789.0, -12345678.9, 1234567.89, -123456.789,
 *                  12345.6789, -1234.56789, 123.456789, -12.3456789, 1.23456789};
 *       int dNumSize = (int)(sizeof(doubleNum)/sizeof(double));
 *       
 *       UErrorCode status = U_ZERO_ERROR;
 *       DecimalFormat* fmt = (DecimalFormat*) NumberFormat::createInstance(status);
 *       fmt->setDecimalSeparatorAlwaysShown(true);
 *       
 *       const int tempLen = 20;
 *       char temp[tempLen];
 *       
 *       for (int i=0; i<dNumSize; i++) {
 *           FieldPosition pos(NumberFormat::INTEGER_FIELD);
 *           UnicodeString buf;
 *           char fmtText[tempLen];
 *           ToCharString(fmt->format(doubleNum[i], buf, pos), fmtText);
 *           for (int j=0; j<tempLen; j++) temp[j] = ' '; // clear with spaces
 *           temp[__min(tempLen, tempLen-pos.getEndIndex())] = '\0';
 *           cout << temp << fmtText   << endl;
 *       }
 *       delete fmt;
 * \endcode
 * </pre>
 * <p>
 * The code will generate the following output:
 * <pre>
 * \code
 *           123,456,789.000
 *           -12,345,678.900
 *             1,234,567.880
 *              -123,456.789
 *                12,345.678
 *                -1,234.567
 *                   123.456
 *                   -12.345
 *                     1.234
