* This is the zero mesher.
* Whatever you want him to mesh, he can't, telling you that by responding with a null pointer.
* Effectivly this is for switching off meshing and for testing as each physics machine should deal
* with the null pointer situation.
* But it's also a convenience thing, as physics machines can rely on having a mesher in any situation, even
* if it's a dump one like this.
* Note, that this mesher is *not* living in a module but in the manager itself, so
* it's always availabe and thus the default in case of configuration errors
