[MOAB-dev] get_entities_by_handle - entities do not include meshset entities

[Tim Tautges (ANL)]

[cc'ing moab-dev because this might be of general interest...]

Ok, yes, that is expected behavior.  The reasoning behind it is that if you're asking to recurse through contained sets, 
chances are you're interested in entities and not sets.  I can see where in some cases this might not be the case, but I 
would still assert that this isn't the more common case.

Note that this behavior is noted in the documentation of the 'recursive' argument to that function, at least in the 
master version (but I'm guessing probably in 4.6 as well, since I don't recall that changing recently).
