/*
    A class to handle the ignition of the detector, in response to the user
    pressing the 'Ignite' button on the easyGUI pages for the FID
    and FPD detector types.

    Note that (as with many other classes in this application) this class is a singleton - 
    we do not need or want there to be more than one instance of it (we do not want 
    multiple ignition attempts going on simultaneously, and nor will we show 
    more than one easyGUI Detector page to the user at the same time).
