% DESCRIPTION: SETPARAMS Set the property 'params' AND 'values'
%
% CALL:        obj = obj.setParams({'a', 'b'}, {1 2});
%              obj = obj.setParams({'a', 'b'});
%              obj = obj.setParams(plist('params', {'a', 'b'}, 'values', {1 2}));
%              obj = obj.setParams(plist('params', {'a', 'b'}));
%
% INPUTS:      obj - one ltpda model.
%              pl  - to set the name with a plist specify only one plist with
%                    only the key-words 'params' and 'values'.
