- * This class expands a string into a list of numbers. The main use is to select a
- * range of pages.
- * <p>
- * The general systax is:<br>
- * [!][o][odd][e][even]start-end
- * <p>
- * You can have multiple ranges separated by commas ','. The '!' modifier removes the
- * range from what is already selected. The range changes are incremental, that is,
- * numbers are added or deleted as the range appears. The start or the end, but not both, can be ommited.
