Class FieldCacheDocIdSet

Base class for DocIdSet to be used with IFieldCache. The implementation of its iterator is very stupid and slow if the implementation of the MatchDoc(Int32) method is not optimized, as iterators simply increment the document id until MatchDoc(Int32) returns true. Because of this MatchDoc(Int32) must be as fast as possible and in no case do any I/O.
