Travis fixed the error he accidentally made when improving MLab.py. This incident points out that our test suite does not include any tests for the non-core modules. Recently the discussion over the meaning of cov shows this too: I didn't even have a test that showed what the INTENDED answer is. We need test suites for FFT, LinearAlgebra, MLab, etc. If you have the subject competence to make a test file for us, please volunteer. I'd like them to be like the ones in Test/test.py, but as a separate file so that I can test the modules separately.
