00102  * Useful for tracking when the control is within a certain method or
00103  * not.  For example, TheoryCore::addFact() uses d_inAddFact to check
00104  * that certain other methods are only called from within addFact().
00105  * However, when an exception is thrown, this variable is not reset.
00106  * The watcher class will reset the variable even in those cases.
