/**
	formValidation
	version 2.0.5
	
	'R'						- required, any value is valid
	'isEmail'				- is email, must be valid email to validate
	'isDatemm/dd/yyyy'		- is date, must be a valid date, valid formats [mm/dd/yyyy, mm-dd-yyyy]
	'isNum'					- is number
	'inRange1:10'			- in range, must be a number in range
	'isPhoneXXX-XXX-XXXX'	- is phone, must be a valid phone, validates phone entered with various chars and sets value to match format
	'isWordCount<=250'		- is wordcount, must have 250 or less words
	'isCheckBox'			- is a checkbox
	
	CHANGE LOG
	2.0.0   - created form validation to validate each form element based on keywords
	2.0.1   - added extensive email validation, instead of just checking for @
	2.0.2   - added phone validation to use regular expression to match numbers and format
	2.0.3   - added browser check to gaurd against netscape behaving badly with string.replace
	2.0.3.1 - added fix for netscape string.replace
	2.0.3.2	- added isCheckBox to allow for required checkboxes
	2.0.4 - added wordcount
	2.0.5 - added IP_SetRequiredBasedOnValue
