A module internal to Incremental. Users should see Incremental_intf.
A stabilization number is an int that corresponds to one round of stabilization (think of a round as running from the end of one stabilization to the end of the next stabilization). Stabilization numbers are used to detect whether a node is stale, i.e. if one of its children changed at a stabilization since the node was recomputed.
