stable papertrail gem setup
extra design added for history /corals/history
trying to create feeds for the changes in paper trail
some basic changes to routes
csv capability added (downloading an old database snapshot)
version controller added... all the versions shown in /history
filtering versions by item_type added in /history
google analytics for tracking csv downloads set up
Added functionality of downloading two files as a zip file (corals.zip + resources.zip) -- need to create a more generic function for all the models
 hirb gem added to prettify the output in rails console -- need to change ~/.irbrc file as well -- instructions in the gemfile
temporary csv files deleted after downloading the zip file from corals
db migrations included in the version control now (removed from gitignore)
respond_to format.csv and format.zip separated... getting corals csv and resources csv are kept into functions
all the models now invoke the application_controller's get_main_csv and get_resources_csv for on-page csv downloads
minor change to test git pull
self.to_csv removed from all the models and added to lib/base_ext.rb which is then included in config/environment.rb .. again emphasizing DRY code
export module exports the data as zip file (main file + resources), removed squeel query from locations controller
Added .uniq to remove observation duplication in users and resources.
Fixing localhost error in help page.
