    MILAD NOTE:
    Right now you can do more than one reaction at a time so it has to be handled here.  
    I might see about adding a small flag to the engine so that if a reaction is currently playing it will end it.
    This will cut down on a lot of boiler code below checking to see if another reaction is playing.  Also because it doesn't
    make sense for more than one reaction to be playing.
