[Biopython] Summer of code update

[Evan Parker]

Hello fellow Biopythoneers and OBF-SoC students,

I have a new blog post <http://evanaparker.com/> regarding my foray into
designing an abstract base for the lazy loading parser classes. My blog
just covers topics that stand out to me, but you can always check out my github
repository <https://github.com/eparker05/biopython/tree/lazy-load> if you
want to see what I'm working on.
