// Declare a global variable and initialize to null.

// This function gets called when the window has completely loaded.
// It starts the reload timer with a default time value.

//window.onload = function()
//{
//  setReloadTime(5); // Pass a default value of 5 seconds.
//}

// setReloadTime() does two different things:
// (1) If a value is passed as an argument, the function clears the current timer
//     (if its running) and starts the timer again with the new time
//     and saves a reference to the timer: reloadTimer.
// (2) If no argument is passed, the page is reloaded. The only time no argument
//     will be passed is when the 'setTimeout()' function times out and calls
//     this function.
