/**
* This code represents the Attribute Pool Object of the original Etherpad.
* 90% of the code is still like in the original Etherpad
* Look at https://github.com/ether/pad/blob/master/infrastructure/ace/www/easysync2.js
* You can find a explanation what a attribute pool is here:
* https://github.com/Pita/etherpad-lite/blob/master/doc/easysync/easysync-notes.txt
