-/**
- * This is a convience or utility class that allows you to make a copy of a
- * part of a larger text store, but have the copy behave as if it was the
- * larger text store.
- *
- * In other words, it provides a subset of a larger document, that "looks like"
- * the orginal document. That is, "looks like" in terms of offsets and lengths.
- * Valid access can only be made to data between the orignal offsets, even
- * though those offsets are in the same units at the original, and even though
- * the length appears to be long.
- *
- * For example, if a subsettext store is created for the def part of abcdefgh,
- * then get(3,5) is valid, getLength is 8. Any other access, such as
- * getChar(2), would be invalid.
