 * Class used to keep track of whether instrumented mock
 * class should use their mocked functionalities, or rather
 * roll back to the original behavior.

 * 
 * This is not really needed during the search.

 * A typical problem happens when "manual" tests are executed
 * after EvoSuite generated ones: we do not want those manual
 * tests to use the mocked versions of the already loaded SUT
 * classes.
