enable_testing()
Introduce structure to the test/ directory This introduces a clear separation between test data and test binaries. Test data is moved into test/data, and the test binaries move into test/src. A new CMake script specific to building the tests is introduced in /test to slightly clean up the toplevel one. As well as tidying things up, this makes the next step trivial...
