[FLASH-USERS] Internal Block IDs

[Anshu Dubey]

They tend to be consecutive in the space filling curve (but not
guaranteed), but not spatially.

You can place a block in the physical domain from cornerId very easily,
there is no direct map back to blockID, because of space filling curve.
There are interfaces that do the backmap for you from coordinates, so you
could translate corner id into a position in the block and use these
interfaces to find blockID. The interfaces are:
