Split long-range calculations into two parts to overcome E-N-potential problems.

The general problem is that smeared-out nuclei charges cannot interact with
electron charge densities as they always overlap, hence we always make a large
error. The idea then is - as the potential energy is symmetric both
densities - to flip from N-E to E-N, i.\,e. to take the electron potential and
evaluate at nuclei positions instead of smeared-out nuclei charges with
eletronic charge distribution. However, then we need to make two calculations
for the four contributions: E-E, E-N and N-N, N-E (=E-N).

  • new enums SampleParticles_t eventually tells InterfaceVMGJob whether to sample the nuclei charges onto the grid or not.
  • TreatGrid_t tells InterfaceVMGJob whether to actually add the electronic charge onto the grid (this was added but is actually not required anymore).
  • FragmentationAutomationAction::performCall() now creates twice as many long-range jobs. This requires two variables in VMGData for storing integrated long-range energy: electron_long, nuclei_long, as both calculations are combined into a single VMGData instance per fragment.
  • Summation of long-range contributions is split into three instead of formerly two parts: electron (E-E), nuclei (N-N), and mixed (E-N). This allows to easierly check their cancellation. This needs new member in fusion map and name in printKeyNames.
  • naturally, the enums have to be passed a long way: VMGFragmentController, VMGJob, VMGData.
  • VMGData now has serialization version 1 due to new entry.
  • we enhanced documentation in FragmentationLongRangeResults::operator()() of how and what is summed per level.
  • FIX: InterfaceVMGJob::ImportRightHandSide() subtracted grid instead of adding it. Now, we set correct sign of electron charge distribution in MPQC.
  • TESTFIX: Regression test AnalyseFragmentResults now has short- and long-range part. Long-range part is only diff'ed when the compiled code has the capabilities.
  • Property mode set to 100644
