//  Purpose: This file provides a standard set of Javascript functions and variables
//           that that are used by the customized Javascript functions in the
//           ShipOnline active server pages.  It contains Browser Detection variables
//           that identify the users browser.  It contains generic functions that
//           allow the developer to "Get" and "Set" values in HTML fields, so they do 
//           not have to worry about the different syntax required the different HTML
//           data field types and browser versions.
//
// Included By: '/ShipOnline/Include/vbScript.vb'
//              (pageHeader function generates client side HTML include statement.
//               when pageHeader is called)
