rearranged the input file a bit and also removed minor hardcoding in SFR_preproc.py
Updated REDME.md
Added CleanupRiverCells.py --> still a bit buggy. Also updated the readme file to indicate this new script and associated steps
Debugged CleanupRiverCells.py
Merge branch 'master' of github.com:aleaf/SFR into mnf
fixed problems with 0 outsegs in interior, and with circular routing between two segments. Improvements to SFR_routing_checker: option to plot all watersheds; projection of output shapefile
incorporated Andy's changes to handle multiple confluences per cell.  Kept out an old way of handling layer bottom checking -- will need to test this.
modified sfr_plots.py due to errors in last line of code: SFR_arcpy.general_join.  Will fetch/merge Andy's original b/c my changes didn't help...  May deal with this later.
tried fetch merge to revert SFR_plots.py, and instead ran into merge problems with readme.md and CleanupRiverCells.py -- not sure why or how it was resolved...
