Detailed Description

VolumeMaterialMapper.

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 Volume with ProtoVolumeMaterial a local store is initialized the identification is done hereby through the Volume::GeometryIdentifier

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

for each track: volume along the origin/direction path are collected. the step are then associated to volume inside which they are. Additional step are created along the track direction.

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