Changed F1 tally bounds

Changed the F1 tally surface to reflect tally over the last end of the
detector instead of about half a cm in the RPM
changed file indent
Collaposed to 8 Quadratures

I collapsed the qudrature down from 16 to eight.  I may go even lower
than that, simply because it makes the input really easy to do.
Initial commit

Added a source spectra with a simple air simulation to make sure that I
can get the source spectra right, or maybe just close enough (for
goverment work).
