* add  "matchcase" parameter to the Classes like :
	PropertyIsEqualTo
	PropertyIsNotEqualTo
	PropertyIsLessThan
	PropertyIsGreaterThan
	PropertyIsLessThanEqualTo
	PropertyIsGreatThanEqualTo
* add "wildcard", "singlechar" and "escapechar" parameter to Class:
	PropertyIsLike
* add More test Case, now passing the xml string has the same result with passing
those constrains by parameter

* remore "wildCard", "singleChar" and "escapeChar" parameters from parent Class.
* fix the bugs that user should also set the "maxrecords"  and "resultType"
