Fixed output file from OscillatedFluxMC.py to output params to the .json file.
Changed downsampling algorithm in utils.py/get_smoothed_map().\n Now it's several orders of magnitude faster.
Major changes: 1) OscillationService class created, \n 2) hdf5 stuff split off into it's own utils/hdf5.py module,\n 3) All oscillation-related code moved to oscillations/ directory.
