+!! 3D BEAVRS benchmark
+!! At HZP, the D bank of rods is partially inserted up
+!! to 15 steps inserted / 213 steps withdrawn.
+!! A step corresponds to an increment of 1.58193cm.
+!! Hence the D bank is inserted by 23.7255cm.
+!!
+!! This could probably be written in a much more efficient and 
+!! understandable way! For example, by being more clever with
+!! transformations.

+  !! Physics package to perform point-sampling-based volume calculation
+  !!
+  !! Calculates relative volume of different materials in the problem by performing
+  !! point-sampling in the geometry. The volume is normalised that the total domain
+  !! volume is 1.0.
+  !!
+  !! Points are sampled uniformly within the geometry bounding box.
+  !!
+  !! This Physics Package exists to serve as a geometry debugging and benchmarking tool.
+  !! Maybe in future it will be useful for burn-up?
+  !!
+  !! Sample Input Dictionary:
+  !!   PP {
+  !!     type pointVolPhysicsPackage;
+  !!     pop 2000;      // Number of points per cycle
+  !!     cycles 100;    // Number of cycles
+  !!     #seed 86868;#  // Optional RNG seed
+  !!     geometry {<Geometry Definition>}
+  !!     nuclearData {<Nuclear data definition. Requires material names only>}
+  !!   }
+  !!
+  !! Private Members
+  !!   geom      -> Pointer to the geometry
+  !!   geomIdx   -> Index of the geometry in geometry Registry
+  !!   rand      -> Random number generator
+  !!   timerMain -> Index of the timer defined to measure calculation time
+  !!   N_cycles  -> Number of cycles
+  !!   res       -> Array to accumulate total number of points in each material. Contains
+  !!     cumulative sum over cycles (CSUM) and cumulative sum of squares over
+  !!     cycles (CSUM2)
