Remove Boost Test and replace with Google Test

This looks great, JS -- I'm really happy to see boost evaporating! One suggestion: rather than using Google's TEST macro use GTEST_TEST. TEST is a mistake Google made (in violation of its own standards I think) in creating a macro with such a common name that it conflicts with other code. Hence the need for this kludge in the google test manual. Other mistakes were SUCCEED and FAIL. I suggest defining the provided GTEST_DONT_DEFINE_TEST etc. macros to avoid the potential for clash with third party or user code.

That's a good suggestion! Done.
