 * A simple test for SolverEngine::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.
