/** @file typed-counter.hpp
 ** Creating sets of type-based contexts.
 ** The idea is to get a "slot" for any given type, so we can build
 ** tables or families of implementations based on these types. Currently,
 ** the slot allocation is based on static variables and thus is global.
 ** This leads to a waste of slots, as the various clients of this service
 ** typically will utilise different sets of types.
 ** @todo WIP WIP... this is the first, preliminary version of a facility,
 **       which is expected to get quite important for custom allocation management.
  ** 
 ** @see typed-counter-test.cpp
 ** @see TypedAllocationManager
 ** @see AllocationCluster (custom allocation scheme using a similar idea inline)
