/* 
Readable version of the Javascript/common.js file 

The "Javascript/common_unpacked.js" file must contain the latest changes.

Compressing JS code:
==================
Requirements:
1) Two script libraries:
	- Javascript/common.js					(file downloaded by browsers, when live, it must be compressed/compacted)
	- Javascript/common_unpacked.js  	(this file - readable version)

Steps:
1) Make necessary changes to JS code below.
2) Fully test that the js code is working
3) Check requirements listed above have been met.
4) Copy this file contents and pasted into a JS compactor/compressor website
		Use http://javascriptcompressor.com/ a compressed version
5) Paste compressed js code into Javascript/common.js
6) Save ...
7) Smile!
