public class BooleanClosureWrapper extends Object
Closure and 
 convert the result to a boolean. It will do this by caching the possible "doCall"
 as well as the "asBoolean" in CallSiteArray fashion. "asBoolean" will not be 
 called if the result is null or a Boolean. In case of null we return false and
 in case of a Boolean we simply unbox. This logic is designed after the one present 
 in DefaultTypeTransformation.castToBoolean(Object). The purpose of
 this class is to avoid the slow "asBoolean" call in that method.
