Memory tests

Look at using Memlab to validate that the internals are appropriately working with garbage collection.

Some example tests:

• Create a loop, create a molecule in each iteration, use it, then discard it. Make sure there's no memory leak.
  • Create a bunch of scopes
  • Create a complex dependency tree of scopes & molecules
  • Same with interfaces
