No "DescribeMyself" in GateVVolume

[Supernabla]

I've noticed that some GateVVolume descendants, e.g. GateTessellated or GateTetra, implement a DescribeMyself(size_t indent) method. However, to me it looks like a dead end, since GateVVolume does not have a respective virtual method GateVVolume::DescribeMyself(size_t).

I think the idea is to extend GateVVolume::Describe(size_t) with information about the specific volume creator, but at the moment this is not impelemented.
