Committing two new files, FDSNSNCL and FDSNFactory. The factory is modeled after the MiniseedFactory with the additional functions that retrive azimuth and dip. The Factory also relies on the get_waveforms method of obspy instead of get_timeseries. The instrument response is also attached and then that response is altered using the remove_response method in Obspy. This returns the response in nT, but we may have to change this depending on whether there are variometers with a frequency response. The __init__.py file was also edited to incooporate the FDSNSNCL and FDSNFactory.
