Allocator that allocates memory from a space heap.
Note that this allocator may be used to construct dynamic data structures that allocate memory from the space heap, or even reside in the space heap as a whole.

Allocates storage.
Returns a pointer to the first element in a block of storage count*sizeof(T)
bytes in size. The block is aligned appropriately for objects of type T. Throws the exception bad_alloc if the storage is unavailable.

Returns a pointer to the first element in a block of storage count*sizeof(T)
bytes in size. The block is aligned appropriately for objects of type T. Throws the exception bad_alloc if the storage is unavailable. The (unused) parameter could be used as an allocation hint, but this allocator ignores it.
