// Newtimer.js version 1.0

// These four functions will take the time till expiration + 1s (expireat) and at that time send a request to jpartner
// That request will not reset the expiration for the session.
// Because of the specialized request, Jpartner will response with one of two choices
// Logged in users will get an XML response back that indicates the new time of expiration.
// At that point, the js will effectively start over with the new expiration time.
// Logged out users will be a standard response back.  At that point the JS will clear the screen,
// inform the user they've been logged out, and then reload the window on their confirmation.
// Also included is the standardized function parseXML which will search a DQ for the text value of a given node.
