Changes 4/4/14

Ruby:

• Kevin emailed me explanations of how classbuilder objects would function in ruby.
• I looked over the processFile.rb code.  It kept giving me an error about not finding a .xml after unzipping
• Eventually I realized it was because I was passing it the command line arguments "download" and "extract", but extract referred to extracting the NSF data, while I meant to pass "unzip" to unzip the file
• Switched the processFile.rb download server from reedtech to google and pushed it to my repo.  However, I accidentally did two commits (one which changed the server and another where I removed test code I had left in).  I don't think there is an easy way to merge them into one.
