expanded functionality to include DFT and iDFT methods as well as a simple PSD estimation method. These are not necessarily ideal, and they should include some sort of window to remove edge affects from the DFT. Also implemented some re-sampling algorithms of dubious merit.
added a few new functions to help visualized the intermediate data products produced by the pipeline.
fixed a bug with mle_strain(invA_dataB!=None), which should work now
added to diagnostic capabilities, including plotting intermediate data products along with writing them to file. Also changed the "verbose" print statements to make them a bit clearer
new file to hold all dft,psd,resampling utilities
fixed a problem with pointers to psd objects. Also defined look-up dictionaries a bit better
added waterfill_mp placeholder, although this only works with a single processor right now
added some I/O utilities for finding frames and reading vectors from those frames
debugged some of project and wrote a few other simple plotting options
moved this far enough that it can run from start-to-finish on real data. Preliminary tests show that it is not able to construct accurate posteriors and is determinant dominated for the vast majority of signals. More testing and better model selection are needed.
