Syncing up dist folder with changes made in array_runtime.js -- they fell out of sync because I only added comments to array_runtime.js so I didn't bin/build
Removed comments that discuss now-nonexistent issues
Added code from CSV-JS library to CSV.js file in lib folder. Modified bin/build to include this file in the pluginlibs variable. Updated the createArrayFromCSV function in array_runtime.js to use the CSV-JS library. Currently running into issue on Safari & Chrome (but not Firefox), where the str variable in CSV.js is being seen as undefined.
Merge branch '667_data_analysis_blocks' of https://github.com/waterbearlang/waterbear into 667_data_analysis_blocks
