/**
 * Provides access to a UUID to be carried through a request response sequence in the cluster
 * This device lets us serialize and transport a request and identify it once a result returns.
 * There are one of these for each node in the sense that the IDs are monotonic from 0 in each
 * instance of this class.
 * The other function is to determine whether the subclassed message gets propagated to nodes, or is a local operation
 * or a split operation such as commit, where there is a local and remote component of different functionality.
