function mfe_loadf_plotperiodogram(stochc,obj);
%MFE_LOADF_PLOTPERIODOGRAM Auxiliary routine for MFE_LOADF.
%	MFE_LOADF_PLOTPERIODOGRAM(STOCHC,OBJ) plots the periodogram of the  
%   stochastic component STOCHC of Model A (or Model B). OBJ is a handle to 
%   the radiobuttons used to select between the models.
