Model Configurator & Automated Testing

This release adds a model configuration utility to the example Tx model, as well as some preliminary automated testing.

You will need to have Python installed, in order to take advantage of either of these two new features.

Note that you can still build the example models the "old" way, by hand editing the *.CPP files. You are not required to use the new Python tools, in order to just build DLLs and/or SOs.
