5: calculate energy
recognized energy calculation modes:
OneStepEnergy : calclulate frozen potential band energy in one step (don't converge Ef)
use only if the Fermi energy will not change due to MC steps!
The only method available in LSMS_1.9
MultiStepEnergy : calculate frozen potential band energy after converging Fermi energy
This should be the new default method. If the Fermi energy doesn't change
multiStepEnergy only performs one step and should be equivalent to oneStepEnergy
The tolerance for Ef convergence can be set with LSMS::setEfTol(Real).
The default tolerance is set in the LSMS::LSMS constructor (currently 1.0e-6).
The maximum number of steps is read from the LSMS input file 'nscf' parameter.
ScfEnergy : this will calculate the selfconsistent total energy.
The maximum number of steps is read from the LSMS input file 'nscf' parameter.
NOT IMPLEMENTED YET!!!
