Benchmark results on mdds::multi_type_vector

[Kohei Yoshida]

I just finished my benchmark testing on mdds::multi_type_vector, and
summarized my results in this blog post:

Hopefully my findings and intepretations make sense.  In short, the
numbers look great.  The overhead of block shifting is a concern, but
I'm optimistic that this is going to be a non-issue for the most part.
