[GSoC] GSoC python variant update 3

[Lenna Peterson]

Hi all,

Latest blog post here: http://arklenna.tumblr.com/post/23630012065/week-1

Brief summary:

I have reversed my prior conclusion that `SeqRecord` is inadequate for
holding variant data. It is still not ideal, but the advantages of
using an existing native object are substantial, and the disadvantages
can be reduced by creating an accessor for the variant-specific data
within a `SeqRecord`.

I've made an outline of how I would store the information returned by
PyVCF within `SeqRecord` and `SeqFeature` objects. It includes a few
questions about the most logical way to store certain variant
information.


As the coding period has now started, I'll be pushing some prototypes
to GitHub in the near future.
