v1.3 (30.08.2010) 	Added the ability to prevent creating the checkbox for an array of columns - using the variable "arrOfFieldInternalNamesToSkip".
--------------------------------------------
v1.4 (24.08.2011)	Added a new parameter "arrDoNotRender". This is an array of fields passed as an argument to the function "init_Checkboxes".
			The fields in this array will not render as a checkbox, but can be prehidden using the array "arrOfPreHiddenColumns" or passed as an argument in the URL.
