// popup_window.js
//
//  Javascript object for easily popupping up windows.
//
// Todo:
// 1. set a default height and width.  (I'm not sure what will happen if
//    none is defined.)
// 2. better creating of the window option string to give to window.open
//    command.  (Check to see if the arguments (height, weight, etc.) are
//    defined or not before using them.)
