% DESCRIPTION: TESTCALLERISMETHOD hidden static method which tests the 'internal'
%              command of a LTPDA-function. This means for example that the
%              method doesn't add history to the object.
%
% CALL:        'normal' command
%                 out = ltpda_uoh.testCallerIsMethod(@fcn, arg1, arg2, ...);
%
%              modifier command
%                 ltpda_uoh.testCallerIsMethod(@fcn, arg1, arg2, ...);
%
% INPUTS:      fcn:  Function name you want to test
%              args: Input arguments for the function
