introduced itmin parameter for spectral code for defining minimum number of cycles 

removed simplified_algorthim flag because the basic scheme using the polarization field will not be implemented
introduced divergence_correction flag for making divergence criterion resolution-independent (still experimental and not set by default)
corrected output and restart frequency (now modulo on incs of current load case)
