MeshTopology uses too much memory when initialising D-1
Issue #185
resolved
MeshTopology uses a lot of memory, especially in 3D, because it generates the connectivity D--D via D--0--D, when mesh.init(D-1) is called.
Probably this can be removed by using a different method, similar to that used in GraphBuilder.cpp
Perhaps connectivities between the same dimension should only be created when explicitly asked for?
