  Rewrite the unit testing suite NIH Enterprises presents: a new testing system based on CuTesT, which is faster than our previous one and fortunately uses no preprocessing on the source files, which means we can run that from CMake. The test suites have been gathered together into bigger files (one file per suite, testing each of the different submodules of the library). Signed-off-by: Vicent Marti <tanoku@gmail.com>
