This class can generate CAPTCHA images with math operations.

It can generate a random math expression with an operation between two numbers, like addition, subtraction and multiplication and render it in a image for CAPTCHA validation.

The class can validate the math expression result entered by the user in a form by comparing with the numbers and the operator stored previously in session variables.
