The payload of a std::vector<T> is aligned appropriately for T. However, there are some times when one would like to force a larger alignment, for example if the vector is being used to hold data to be processed with vector instructions. aligned_vector defined here is a std::vector with higher alignment. vec_aligned_vector is a vector that should be sufficiently aligned for any vector instructions on this platform.
