//	*	File Name :		olrjslib.js																	   *
//	*	Version :		1.0.0.0																		   *
//	*	Created By :	Martin Holly																   *
//	*	Last Updated :	01/13/09																	   *
//	*	Updates :																					   *
//	*	01/19/09	- OLRBasicSelect.SetValues now does not create a default option specified by 	   *
//	*				  "label" argument if "label" is null or empty string.							   *
//	*	02/04/09	- Added ArrayList object. This is a rudimentary array object with a couple of 	   *
//	*				  usefull functions: AddValue(v), RemoveAll(v) and RemoveOne(v)					   *
//	*	02/05/09	- Added the functions IndexOf(v), Copy() and AddRange(arr) to ArrayList			   *
//	*	02/12/09	- Added the Pager object. This is allready pretty well developed.				   *
//	*	02/24/09	- Added the MortgageCalculator object. This is still not completely fool proof.	   *
//	*	03/07/09	- Added the ability to have a template divider for the Pager object. The 		   *
//					  constructor takes an optional 5th argument that can be an jQuery object or a 	   *
//					  string html representation.													   *
//	*	03/16/09	- Added the previous & next button separator for the Pager object. 				   *
//	*				  This is the 6th argument.														   *
