testing: new strategies test with half-patched ._setup_cluster method
testing: starting to test strategies (hard, because they are interactive) and pushing out a BoundingBox class for the Problem class (sub-classing np.ndarray doesnt work, never try it again). Also adding few more tests, comments and cleanup
future-rizing the code to make it 3.x compatible
fixing details such that full test suite runs again
adding future to requirements
