Description

At CM38 Adam mentioned a slow memory leak in MAUS.

Indeed, there do seem to be leaks.
On my machine, running offline reconstruction on a smallish data-set [ 04995.000 ], the memory usage climbed from 180MB to 550MB
[ memory monitor log attached ]

Valgrind shows some stuff coming from Python, ROOT and GEANT.
On the MAUS side, there seem to be lots of leaks from G4 DetectorConstruction, Globals, JsonCpp converters
