Unit tests require tcc executable in path

[tranqui]

Unit tests fail on @merrygoat's windows machine because the unit test assumes the tcc executable is in the system path. Solution requires either an install feature (e.g. make install as suggested in #59), instructions for adding to the path or a workaround this requirement e.g. by directly locating the executable within the python front end.

Python front end should locate the executable inside the bin folder (if it has been built) as of 7a8a67d

@merrygoat do the unit tests run for you now?

[merrygoat]

They did not. I have made some modifications on the new branch "unit_tests".

For me the unit tests now pass on all three platforms. It would be good if you could have a look and see what you think. 7T is also now passing, hopefully that method is complete.

The integration tests are borked atm. because of adding the 7T, I will update these and the static_clust file Monday, integrating some of your ideas from the unit tests.

Confirmed that they are working. I have merged changes into devel branch.
