Too many false positives/results have letters and symbols #111

What steps will reproduce the problem?
1. Ran a basic scan using standard Visa, Mastercard, AMEX RegEX.

What is the expected output? What do you see instead?

I would have expected results resembling credit card numbers.  Instead I'm 
seeing results with patterns such as:

Visa    XXXXXXXXXXXXXXXX237C
Visa    XXXXXXXXXXXXXX417<
Mastercard  XXXXXXXXXXXXXX475<
Mastercard  XXXXXXXXXXXXXX594?
AMEX    XXXXXXXXXXXXX495<
Visa    XXXXXXXXXXXXXX704D
Social_Security_Number_dashes   XXXXXXXXXX33-
Social_Security_Number_spaces   XXXXXXXXXX17T

What version of the product are you using? On what operating system?

0.5.1 on OpenDLP pre-built VM (Ubuntu 11.04)

Please provide any additional information below.

I am testing out OpenDLP on one system that I know is free of CC information, 
yet it is showing over 500 findings (and the scan is only 13% complete).  All 
of the findings are like the above.

As a feature request, is there any way to have the program include the Luhn 
algorithm to help reduce false positives on CC numbers?

Thank you.
