Begin the traversal.

This routine is called per spacetree instance, i.e. per subtree (thread) per rank. Within the usual implementation, everything will reside on the call stack anyway. If the routine is called on tree no 0, this operation has to establish the master data of the global root tree, i.e. ensure that the data of level -1 is technically there for the subsequent enterCell event, though this data is ill-defined.
