Detailed Description

A user action used to evaluate thickness of all detectors traversed by outgoing particles.

This user action is currently used only in special runs with geantinos. Thickness is recorded in terms of both rad length and int length.

NOTE: the current design is safe for multi-threading, but not performant due to sharing of the histograms and excessive locking. If this action needs to be used in multi-threaded jobs, we can rewrite it so that each instance has its own copy of the histograms which get merged in finalization of the LengthIntegratorTool.
