 * Class MemoryManager: allocates/deallocates memory for objects of a
 * requested size.  Some instanced of this class may be specialized to
 * a specific object size, and the actual memory may be allocated in
 * big chunks, for efficiency.
 *
 * Typical use of this class is to create 
 * MemoryManager* mm = new MemoryManagerChunks(sizeof(YourClass)); 
 * where YourClass has operators new and delete redefined:
 * void* YourClass::operator new(size_t size, MemoryManager* mm)
 * { return mm->newData(size); }
 * void YourClass::delete(void*) { } // do not deallocate memory here
 * Then, create objects with obj = new(mm) YourClass(), and destroy them with
 * delete obj; mm->deleteData(obj);
