Initial commit
Some r changes, start at py script for grading

Asking again for grade if used editor to modify
Rscripts to deal with smartsite xls

1 convert smartsite xls to csv,
2 convert section csv to simpler format for use as LUT
Function for opening subs, writing to file on exit, better cl try/catch
Fixes to flow control, break out editing comments and grade to sep functions
Lookup table for the section membership and grading only certain sections

For now, only one or all sections may be specified.
Lookup working, handling keyerror semi gracefully

Still lack robustness seriously with cli args.
Rewrite commandline arguments to use argparse
Redo args to make section specification optional

(and have dependence between specifying a section and having a look up table
for sections and student user names)
Merge branch 'master' of github.com:ashander/smartersite

Adding .gitignore, license, README for upload
