CSPM.Renamer
Description
Renames all variables to unique Names, in the process converting all UnRenamedName into Name. This simplifies many subsequent phases as every name is guaranteed to be unique so flat maps may be used, rather than Hierarchical maps. Further, this also flags patterns that match channels and datatype clauses.
