* common.js
* Included JavaScript supporting common page functions.
*
* Note:
	4/21/04 - In VSS common.js is stored as common\control\js\common.js and
						is shared to other projects. 
						This shared link between projects should not be branched
						Sharing common.js between projects allows the developer to
						make his changes once and "get latest" to update other projects.
						Additional Note: When deployed there will be multiple copies of
						common.js.
