* added a DeprecationWarning if a Simulator is garbage collected without
having its .close() called
* renamed all gc __del__ callbacks to close()
* implemented context manager hooks for Simulator. Use like
with Simulator(TestBench()) as s:

group_by_target does not properly combine target groups if statements

({A, B}, statement3)
which returns groups:

({B}, [statement2])
