Replace AlignedBuffer with more general Align (#80)
Replace AlignedBuffer with more general Align (#80)

Rename `AlignedBuffer<T, B>` to `Align<T, A>`. The former is a `B`
aligned to at least `align_of::<T>()`, while the latter is a `T` aligned
to at least `align_of::<A>()`. They're functionally equivalent, but the
latter isn't documented in such a way that implies that it can only be
used for buffers.
