   #    Escapes strings that may have embedded 's that will be put into
   #    strings as 'strings'.
   #    The assumptions are:
   #       There has been no effort to escape ' with \'
   #       Any \'s in the string are intended to be there as part of the URL
   #        and must also be escaped.
   # Parameters:
   #     input     - The string to escape.
   # Returns:
   #     The escaped string (' replaced by \' and \ replaced by \\).
   #

   #     input     - The string to escape.
   # Returns:
   #     The escaped string (" replaced by \" and \ replaced by \\).
