Poll Engine: Build and process polls stored in a database

This class is meant to build and process survey polls with definitions and results stored in a database.

It uses the ezSQL class by Justin Vincent and the Template Engine class by Jonas Lasauskas. To use the PollEng class you need to have these two classes and your site must be built with the Template Engine class.

This class allows you to:

- read the poll data from the database
- display the poll (question or results)
- update votes in the database
