// Cross Browser DOM External File 
// Filename: findDOM.js
//   Due to the differences in how the major browsers implement the DOM
//   it is necessary to detect the browser by testing for the particular
//   DOM supported. Each DOM is tested and returns the correct root 
//   DOM statement that matches the browser.
//   After first DOM is supported, testing stops.

var isLayers = 0;    // 1 if browser supports Netscape DOM
