// return reference for vector and matrix types to allow things like

// returning value would only change copy of velocity, without propagating back to the original

// see http://www.mail-archive.com/yade-dev@lists.launchpad.net/msg03406.html

// note that for sequences (like vector<> etc), values are returned; but in case of 
// vector of shared_ptr's, things inside are still shared, so
// O.engines[2].gravity=(0,0,9.33) will work
//
// OTOH got sequences of non-shared types, it sill (silently) fail:
// f=Facet(); f.vertices[1][0]=4
