/*
 
This routine checks the credit card number. The following checks are made:
 
1. A number has been provided
2. The number is a right length for the card
3. The number has an appropriate prefix for the card
4. The number has a valid modulus 10 number check digit if required
 
If the validation fails an error is reported.
 
The structure of credit card formats was gleaned from a variety of sources on 
the web, although the best is probably on Wikepedia ("Credit card number"):
 
  http://en.wikipedia.org/wiki/Credit_card_number
 
Parameters:
            cardnumber           number on the card
            cardname             name of card as defined in the card list below
