test_subset_region — Test whether a region is contained in another region.
test_subset_region tests whether Region1 is a subset of Region2 and returns the result in IsSubset. If more than one region should be tested, Region1 and Region2 must have the same number of elements. In this case, a tuple that contains as many elements as Region1 and Region2 is returned in IsSubset.
Region for comparison.
Number of elements: Region1 == Region2
test_subset_region returns the value 2 (H_MSG_TRUE) if the parameters are correct. The behavior in case of empty input (no input objects available) is set via the operator set_system(::'no_object_result',<Result>:). If the number of objects differs an exception is raised.
