@ingroup heap Perform a random walk of the tree. The walk is biased towards elements closer to the root of the tree (since each walk starts at the root and ends at a random leaf). The heap internally tracks the current position of the walk.

@param heap heap to walk @return data stored at the next random node in the walk; NULL if the tree is empty.
