** \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.
