/* 
Window Launcher for Cairns Regional Council.
Author: Nathan McCarthy, October 2008.
    
    Use a HTML element's "onclick" event handler to launch the window.
    
    There are three parameters:
    
        1: window size: 'reg', 'large', or 'auto'.
        2: work context: Any valid work context. Specifying an invalid context appears to just load with the default.
        3: (optional) URL: pre-pends the url to the launcher to allow launching from other web locations
    
    Examples of basic links follow:
    
        <a href="#" onclick="javascript:launch_window();">
            Launches a window without specifying the size or the work context. A basic 'online maps' link.
        </a>

        <a href="#" onclick="javascript:launch_window('reg');">
            Launches a regular sized window without specifying context.
        </a>

        <a href="#" onclick="javascript:launch_window('large', 'Aerial Imagery');">
            Launches a large-sized window using the Aerial Imagery work context.
        </a>
