Carfac C++ revision 3, indluding more style improvements. The output structs are now classes again, and have separate storage methods for each output structure along with flags in the Run and RunSegment methods to allow for only storing NAPs if desired.

Test for the Gaussians module. Runs a number of pre-computed SAI profiles
through the module, and tests them against the saved output from the
MATLAB rubber_GMM code.
