Added Request to Archive document, which details sftp requirements and data file naming convention, file size, time averaging, etc.
Added a new directory in the 'idl' and 'data' repositories (judith_2014_08_21) to hold Judith's most recent version of the NRL2 model code and the most recent version of the model parameters. There is also new output to compare too.
Made new idl directory, 'irradiance', to hold NRL2 model code to compute TSI and SSI for a given sunspot blocking (sb) and magnesium (mg).

Broke Judith's original NRL2 code, nrl2_21_Aug14.pro, into functional routines:
 1. get_model_params.pro
  2. get_spectral_bins.pro
  3. compute_tsi.pro
  4. compute_ssi.pro
  5. bin_ssi.pro
  
 Successfully re-created the data output totirrad, nrl2tot, and nrl2binsum when compared to Judith's original NRL2 code (see above).
Changed directory path.
