@blakewalters @mainegra this pull request is in conflict with #974 (add dbs to radiative splitting). Since the latter is still a draft, I suggest that we merge and then resolve conflicts in the |

I agree, @ftessier, let's get this merged in before worrying about DBS splitting, which shouldn't be affected by this change in any case. |

Initial radiative splitting naively just turned ON EGSnrc internal
flag nbr_split to split brems and annihilation events uniformly.
However no charged particle RR was played after pair production (i_play_RR)
nor were secondary photons, produced by charged particles surviving RR after
bremsstrahlung, split.
--------------------
Radiative splitting:
--------------------
now turned ON before a bremsstrahlung event for a primary or a fat charged
particle. It is turned OFF after the brems event to avoid higher order
splitting. Fluorescent fat photons, generated by fat charged particles
(survived RR) are also split.
NOTE: Not done for annihilation yet! Coming up!
This time RR is turned ON using EGSnrc internal flag i_play_RR so that RR is
played after pair events. RR can be turned OFF by entering a negative splitting number.
NOTE2: Brems events play RR intrinsically hence it can't be turned OFF.
Setting i_plpay_RR affects pair production ONLY.

- Split annihilation in flight and at rest events for primary and fat positrons.

Implement radiative splitting + RR
Now turned ON before a radiative event for a primary or a fat charged particle.
Turned OFF after the event to avoid higher order splitting. Fluorescent fat photons,
generated by fat charged particles (survived RR) are also split.
RR is turned ON using EGSnrc internal flag
i_play_RRso that RR is played after pair events.RR can be turned OFF by entering a negative splitting number.
NOTE2: Brems events play RR intrinsically hence it can't be turned OFF.
Setting
i_play_RRaffects pair production ONLY.Other minor changes:
egs_dose_scoring.cppremoved the statement printing media names during dose output to the screen for dose to medium calculations. I have re-added the line.egs_dose_scoring.cppchanged the header formatting when outputting media doses which misaligned it.
