Detailed description

This package can be used to implement CAPTCHA validation using text with math expression.

There is a base class that can display a text message to tell the user what he needs to input.

A math subclass generates an expression with a random math operation between two number values.

The user must enter the result of the operation to pass the CAPTCHA validation. The correct answer is stored in session variables for posterior validation.
