<!-- test that history states works correctly.  The counter Var1 counts how many times
we have entered s0.  The initial state is s012.  We then transition to s1, which transitions
to s0's deep history state.  entering.s012 should be raised, otherwise failure.  Then we transition
to s02, which transitions to s0's shallow history state.  That should have value s01, and its initial
state is s011, so we should get entering.s011, otherwise failure.-->
