/************************************************

DESCRIPTION: Validates that a string contains only 

    valid dates with 2 digit month, 2 digit day, 

    4 digit year. Date separator can be ., -, or /.

    Uses combination of regular expressions and 

    string parsing to validate date.

    Ex. mm/dd/yyyy or mm-dd-yyyy or mm.dd.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.
