Qube command and cartesian F functions

qube.app
  Ths is a port of OpenQube's tool. It uses QuantumIO to read
  the output file and prepare the MO or density.
  For now the dimensions of the qube are hard-coded.
  Some cout printing from QuantumIO has been disabled to create
  a clean qube.

Cartesian F functions
  So far it has been tested with GAMESS-US.
  The QuantumIO reader will reorder the coefficients before they
  are loaded into the GaussianSet.
  f-only.gamess in avogadrodata will generate a correct qube.
