ImpactSphere:
  Modified ImpactSphere to exploit radial symmetry

OptimizerLib:
  Changes in OptimizerLib that reads the correct (mass)density and averages it
  over the foam*

  Slight Change in generateGPInfo & runMCTest ass well as the
  optimizer.py (driver), that enables (mass) density evaluation using
  the dspace vector and radius to volume fraction conversion

 * Foam is the pseudoname for the bulk containing the lattice, If you
   come up with a better naming convention, I remain open for
   suggestions
