First draft of python based tests

[Luv2C0d3]

NOTE: Still work in progress, if ok, we should possibly add more tests.

Good day. This is a different approach to providing some tests. This approach is less invasive in that it uses just a small python program to test tinylisp or any of its siblings. I put things in a test folder as you requested, to keep it out of the main workflow and keep things simple.

Pros of this approach:

• Less invasive.
• Easier to put in practice as it uses a scripting language.
• Written in simple python code to make it easy to understand.
• Should work unchanged in Windows, except for invoking it with python test_runner.py instead of just the script as can be done in Linux.

Cons:

• I cannot unit test things in depth as I can do in a C based test.
• It is not written in C and requires some Python knowledge.
• It spawns one program instance per test. This should not be too much of a problem as it still runs very fast because tinylisp loas very fast.

Anyhow, tell me what you think? We could use this approach or if there is value a mix of Python + C tests, but for now it seems only one should be sufficient.
