/******************************************************************************
 qForm JavaScript API

 Author: Dan G. Switzer, II
 Date:   December 10, 2000
 Build:  140

 Description:
 This library provides a API to forms on your page. This simplifies retrieval
 of field values by providing methods to retrieve the values from fields,
 without having to do complicate coding.

 To contribute money to further the development of the qForms API, see:
