	DESCRIPTION: Validates that a string contains only

	    4 digit year. Date separator can be ., -, or /.
	    Uses combination of regular expressions and 
	    string parsing to validate date.
	    Ex. dd-mm-yyyy
	    
	PARAMETERS:
	   strValue - String to be tested for validity
	   
	RETURNS:
	   True if valid, otherwise false.
	   
	REMARKS:
	   Avoids some of the limitations of the Date.parse()
	   method such as the date separator character.
