Detailed Description

SurfaceMaterialMapper.

This is the main feature tool to map material information from a 3D geometry onto the TrackingGeometry with its surface material description.

The process runs as such:

1) TrackingGeometry is parsed and for each Surface with ProtoSurfaceMaterial a local store is initialized the identification is done hereby through the Surface::GeometryID

2) A Cache is generated that is used to keep the filling thread local, the filling is protected with std::mutex

3) A number of N material tracks is read in, each track has : origin, direction, material steps < position, step length, x0, l0, a, z, rho >

for each track: surfaces along the origin/direction path are collected the closest material steps are assigned

4) Each 'hit' bin per event is counted and averaged at the end of the run
