Detailed Description

template<typename T>
class fei_Pool_alloc< T >

fei_Pool_alloc (along with its underlying memory-pool class fei_Pool) is taken almost verbatim from Stroustrup's book "The C++ Programming Language 3rd edition", pages 567-572.

The difference between this class and the one in the book is that the length of allocated memory-chunks must always be the same. That is, the first time allocate is called, an internal memory-pool is created with the specified alloc-size. That memory-pool can only satisfy allocation requests of that same size from then on.
