Detailed Description

Token Invariants.

The Token Invariant Manager allows applications to test that invariants are always satisfied. Currently, Token_Invariants can test mutexes and readers/writer locks. Does not test recursive acquisition. Note that this class does not ever clean its database. Until destroyed, it's size will forever increase.
