- Unbreak the three broken tutorials (fixes #848) - This involved a rewrite of PPP-01-10 because I already had my own solution to that one and I couldn't easily tell what was going wrong with the previous solution. - Add assertions to all the tutorials so that non-raising means success - Add the TTT examples to `test_examples.py` added recently for #909 - Also added sympy to development dependencies since one of the TTT examples uses it.
