My first commit
Updated the String split and added more Country names into the
CountryNameToCountryCode class.
Trying to add the files
Replace MongoDB with AMQP
Rewrite collector to CoffeeScript
Refactor, extract GitHubClient class
Cleaned up commented code. Added hashmap cache(mapping addresses to iso
numbers).
Fixed some comments and prints.
Add location to events
Filter events considered contributions
Functions for converting percentages to a hex-color code for the heatmap. Added some comments in the index.html file
Worker is now reading Json files from a queue, getting the iso number
with help from the other classes , and adding it to the Json file. For
som reason the values in the Json file are also reorderd, but I can't
see how this would create any problems. I have added a bunch of error
handling if-statements that hopefully will keep the program from
crashing too easily.
