Minor fix for the min-dist mapping algorithm: we need to call 'get_nbobjs_by_type' first, before we get the sorted list of nodes - we need to add node objects and fill them in the summary object for the current topology. This patch was submitted by Elena Elkina and pushed by Josh Ladd. This should be added to cmr:v1.7:reviewer=jladd
