% DESCRIPTION: SETCHI2 Set the property 'chi2'
%
% CALL:        obj = obj.setChi2(37);
%              obj = obj.setChi2(plist('Chi2', 37));
%              obj.setChi2(37);
%
% INPUTS:      obj - can be a vector, matrix, list, or a mix of them.
%              pl  - to set the 'chi2' with a plist specify only one plist with
%                    only one key-word 'chi2'.
