 ** \brief A simple test for SmtEngine::resetAssertions()
 **
 ** This program indirectly also tests some corner cases w.r.t.
 ** context-dependent datastructures: resetAssertions() pops the contexts to
 ** zero but some context-dependent datastructures are created at leevel 1,
 ** which the datastructure needs to handle properly problematic.
