AXMLS Release 1.0.1

Hot of the tail of 1.0, we've folded in a couple of tidbits for a 1.0.1 release. The main reason for the quick 1.0.1 release is to remove the PHP-XSLT requirement added by version 1.0. PHP-XSLT is now optional, and only required for the (as yet) little-used schema transformation utilities. Along the way we've added inline schema execution and a new tutorial: Using AXMLS.
