Initial button functions
        These buttons control the setup of phat.C before the event loop starts. They appear during a delay loop before the loop start and after some defaults are set which the buttons can alter. The aqua color buttons allow you to change the input and output files; the TG**** file selector planned is not yet working so you will have to type on the ROOT command line. They also allow changes from the large default number of events and runs (latter not yet used). The blue buttons activate tasks. For example, R.V. can click on Vtx, Mul, and DST if output is wanted, without requiring any spectrometer tracking code (Spc) etc. GO exits the delay loop and starts the event loop with the parameters set here. If no task buttons have been pressed GO presses all of them for you. Finally, HELP brings up these html pages if BROWSER and PHATHELP are properly defined environmentals (see Setting the Environment). These help pages will in time become more PHOBOS-specific with these phat.C instructions becoming only one of many subtopics.
