Notes:
Gorille 0.3 now supports surrogate pairs in XML documents. These are not permitted in XML 1.0, but are permitted in the current draft of XML 1.1. The API works the same, but all char parameters are now int parameters.
Changes:
Updated CharRange, CharRanges, and CharRules to use int parameters rather than char parameters. Added logic to CharRules to test for surrogate pairs.
