Changes 4/8/14

Github:

• Learned about modifying/deleting already existing commits

Ruby/Regular Expressions:

• Began working on adding a preference for either reedtech or google's servers
• I wanted to do it as elegantly as possible, so I took a long time and didn't finish
• Basically, the download flag functions as it did, but now one can do download-reed(tech) or download-goog(le). 
• This will then be passed to the url generator.

Code:

1. #should_download = actions.empty? || (actions.include? "download") # old line of code

   # new lines of code:

   should_download = false
   server_preference = "goog" # Default to google
   unless actions.empty?
     actions.each do |action| # Actions is an array of launch options, ex: ["download-goog", "unzip", "extract"]
       should_download   = !(action.match /download/).nil? # is there a better way to evaluate false to nil and true to not nil?
       
       if should_download # break once the download option has been found

         server_preference = action.match(/goog|reed/).to_s # Sets server preference to "goog" or "reed" dependent on dl suffix

         break

       end 

     end
   end
