Function Name: CheckPhoneNumber
Parameters: objToCheck .............object holding the phone number

Logic: The value of the object is passed to ReplaceAllChars to filter
	   all non-numeric numbers out.  Then the returned string is
	   checked for the appropriate length for a phone number + area
	   code (10 numbers).  If longer than 10 the first 10 numbers are
	   used truncating the remaining.  If longer or equal to 10 chars
	   this function inserts the 10 digits into a mask for consistent format.
	   If less than 10 characters the functions throws an ALERT telling
	   the user so and does not mask the numbers.
