// CLIENT-SIDE POPUP WINDOW
//
// Displays custom popup in current web page
// Popup is opened by calling
// new Popup(name, srcUrl, params, onCloseFunction)
// name: popup frame name and id
// srcUrl: Url of page to load in frame (or null)
// params:
//   - posElement: name of element that we want the popup to be aligned with
//   - offsetX, offsetY: offset in pixels to be offset
//   - width, height: popup width and height
//   - sticky: whether popup can only be closed by pressing the CLOSE link (true), or is automaticaly closed when user clicks anywhere on page (false - default)
// onCloseFunction: function to be called when popup is closed (or null)
//
// e.g. new Popup("CalculateTaxPopup", "bla.html", "posElement=CalculateTaxPopup_Position, offsetX=0, offsetY=-200, width=350, height=200, sticky=true, waitOnly=true", MyCloseHandler);
// 
// When constructed, popup is available publicly at window.popupName (any page can access it).
// Popup window should have it's own javascript to handle two things:
// 1. Store return value: window.popupName.Value = value_to_return
// 2. Call method to close popup: window.popupName.Close()
// After this, onClose function will be called (that is provided in Popup.Display method).
// Close function can handle return value stored in window.popupName.Value.
