• Check whether HashKey can be reduced to a simple 32 byte array (see desc_identifiers.nim)

• Remove the RlpData accounts payload type. It is not needed as a separate data type. An application must know the layout. So it can be subsumed under RawData (which could be renamed PlainData.)

• Currently, the data save/store logic only works when there is s VertexID(1) root. In tests without a VertexID(1) a dummy vertex is set up.

• Re-visit delTree(). Suggestion is deleting small trees on the memory later, otherwise only deleting the root vertex (so it becomes inaccessible) and remember the follow up vertices which can travel through the tx-layers to be picked up by the backend store.
