% GET_TEST_OBJECTS_PARFRAC returns a set of PARFRAC objects suitable for many of the UTPs
%
% CALL:     [pf1,pf2,pf3,pfv,pfm] = get_test_objects_parfrac
%
% OUTPUTS:
%           pf1  - parfrac object without direct term
%           pf2  - parfrac object with direct term
%           pf3  - parfrac object with I-/O- units
%           pfv  - [pf1, pf2, pf3];
%           pfm  - [pf1, pf2, pf3; pf1 pf2 pf3];
