Class:      cxaRuleCacheElement
Author:     Alexander Berthold
Copyright:  Alexander Berthold
Date:       2001/12/19
Version:	0.2.01
Purpose:    Helper class for caching failed/succeeded tests.
			Currently only succeeded sub-expressions are cached,
			and only if they are designated as being cacheable
			(ex.: "C{.expr}=100:{.expr}{$+}{.expr}")

Version history:

	-	2001/12/15
		Implemented current version

	-	2001/12/19
		Labeled 0.2.01

ToDo:
	-	Add support for caching data on failed sub-expressions.
