:mrdocs:

Create an `AligningAllocator` object that guarantees alignment by the specified `alignment` (in bytes) of memory allocated. Optionally specify a `basicAllocator` used to supply memory. If `basicAllocator` is 0 or not supplied, the currently installed default allocator is used. The behavior is undefined unless `alignment` is a power of 2, and the alignment strategy of the alocator used to supply memory is `BSLS_MAXIMUM` or `BSLS_NATURAL`.
