+/**
+ * <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
+ *  \endcode
+ * </pre>
