ParticleCounter: unpack 2D array higher in nested loop
ParticleCounter: start implementing more efficient linear approach
ParticleCounter: use Integer.valueOf() rather than new Integer()

ParticleCounter: LUT array approach under test
ParticleCounter: daily commit
ParticelCounter:playing with boolean map
ParticleCounter: massively improve Mapped method by skipping values
ParticleCounter: use ArrayList rather than HashMap
ParticleCounter: do first merging
ParticleCounter: comments with strategy
ParticleCounter: remonder to use proper Iterator to allow modification
ParticleCounter: bring array creation out of the inner loop
ParticleCounter: further reduce array instantiation
ParticleCounter: runs fast but result not correct - incomplete merging
ParticleCounter: minimise LUT array
ParticleCounter: fix bug in applyLUT, add more LUT checks
ParticleCounter: added checks but still about 1% of particles not merged
