31.1.2011 Kamil Sedlak - changes for Geant 4.9.4

Browse Source 
Changes in musrPhysicsList.cc that were needed for new version of 
Geant = Geant4.9.4.  The changes remove G4MultipleScattering and
MultipleAndCoulombScattering,  because multiple scattering has to
be treated differently for different particles in Geant4.9.4 and
"G4MultipleScattering" is not supported anymore.  The documentation
has to be updated (i.e. comments about MultipleAndCoulombScattering
has to be removed from doc/musrSim.tex).

\section{Optical photons}

Normaly the simulation of ``detected signal'' stops at the level of the deposited energy in
a sensitive volume (e.g.\ in a scintilator tile). However, in some special cases, one would
like to know how the light is propagated through the scintillators. In such case simulation

even in this case it is not guaranteed that only a single particle gave origin to the hit, it is quite likely, though,

\item{\bf odet\_n} (Int\_t) -- number of ``optical photon signals'' in this event. Note that there can be several optical photon signals
per detector. In principle, the optical photons contributing to the same signal may originate from more than
one charged particle. Ideally, there should be the same number of optical photon signals as there are
``detector hits'', i.e.\ odet\_n = det\_n. However, detector hits are treated independently of the
optical photon signals, and they do not have to match perfectly.
\item{\bf odet\_ID[odet\_n]} (array of Int\_t) -- ID number of the detector where the given optical photon signal occurred.
The detection of optical photons happens at the boundary of surfaces, and it is assigned to the volume ID \emph{to} which
the photon enters (and not \emph{from} which it comes). This e.g.\ allows one to attach more APDs to one scintillator,
in which case odet\_ID[] will correspond to the volume IDs of individual APDs.
\item{\bf odet\_nPhot[odet\_n]} (array of Int\_t) -- number of photons detected in the given optical photon signal.
\item{\bf odet\_timeFirst[odet\_n], odet\_timeLast[odet\_n]} (array of Int\_t)
-- times, when the the first and last photons contributing to the given signal were detected (odet\_timeFirst and odet\_timeLast).

-- time, when the $n^{th}$ photon was detected, where $n$ for \emph{odet\_timeA[i]} is given as \emph{OPSA\_fracA}
multiplied by \emph{odet\_nPhot[i]}. Similary for \emph{odet\_timeB[i]}, ..., \emph{odet\_timeE[i]}.
The variables \emph{OPSA\_fracA}, ..., \emph{OPSA\_fracE}, are defined by ``/musr/command OPSA photonFractions'' command
(see chapter~\ref{sec:opticalPhotons}).
\item{\bf save\_n} (Int\_t) -- number of special kind of ``save'' volume that were hit in this event. The ``save volume'' is
any volume whose name starts with letters ``save''. Their purpose in the simulation is usually to check positions
and momenta of particles at some position of the detector, even if the particle does not deposit any energy in
