/**
* @class ACE_FlReactor
*
* @brief A Reactor implementation that uses the Fast-Light (FL) toolkit
* for event demultiplexing. This will let us integrate the FL
* toolkit with ACE and/or TAO.
*
* As many other GUI toolkits FL supports a minimal set of
* callbacks to handle event demultiplexing, namely simple methods
* to add file descriptors to the event demuxing set or timeout
* events. This class adapts this simple mechanisms so they are
* compatible with ACE's Reactor.
