 There's a key tradeoff between the two: compilers have a much less difficult
 time auto-vectorizing the SOA implementations, but the AOS implementations are
-easier to read and write. It's not uncommon to see AOS algorithms applied in
-real-world applications (consider, for example, how most object-oriented
-programs are constructed).

-Most of the code is plain C, with some added pragmas to provide compilers with
-appropriate hints to vectorize/parallelize the code properly.
