Detailed Description

template<class T>
class mems::SlotAllocator< T >

This class allocates memory according to the slot allocation scheme for fixed size objects.

Each time all slots are full it allocates twice the previous allocation. If it is unable to allocate twice the previous allocation, it does a binary 'search' for the largest amount of memory it can allocate. The current implementation does not allow memory to be freed once allocated.
