00013     A class to handle the ignition of the detector, in response to the user

00015     and FPD detector types.
00016 
00017     Note that (as with many other classes in this application) this class is a singleton - 
00018     we do not need or want there to be more than one instance of it (we do not want 
00019     multiple ignition attempts going on simultaneously, and nor will we show 
00020     more than one easyGUI Detector page to the user at the same time).
