Folder cleanup

[scotthavens]

AWSM was initially setup with a complex folder structure to account for different potential simulations. While some of it was useful, it created a very deep folder structure. With the IPW version of iSnobal removed from AWSM, this greatly simplifies the folder structure.

All ouput from AWSM will be in the run<date> folder instead of split up across 3 different folders.

|     |____ <water year>

|     |      |      |____run<date>
|     |      |      |      |____<SMRF netcdf files>
|     |      |      |      |____<PySnobal netcdf files>
|     |      |      |      |____logs/
|     |      |      |      |____input_backup/
|     |      |      |____run<another date>

|____ <basin_2>
|     |____ <water year>
|     |      |____ <project name>
|     |      |      |____run<date>
|     |      |      |____run<another date>

This is one of the larger topics in #71

NOTE: This will break the awsm daily runs for ops. @jomey has ideas for consolidating the command line functions which will address the break, see #78
