Compute the morphological skeleton of a region.
morph_skeleton computes the skeleton of the input regions (Region) using morphological transformations. The computation yields a disconnected skeleton (gaps in the diagonals) having a width of one or two pixels. The calculation uses the Golay element 'h', i.e., an 8-neighborhood. This is equivalent to the maximum-norm.

morph_skeleton returns 2 (H_MSG_TRUE) if all parameters are correct. The behavior in case of empty or no input region can be set via:
a) no region: set_system('no_object_result',<RegionResult>)
b) empty region: set_system('empty_region_result',<RegionResult>)
Otherwise, an exception is raised.
morph_skeleton is reentrant and automatically parallelized (on tuple level).
