Added a Reading List to blacklitterman.org

I've added a reading list RSS feed at blacklitterman.org. It's just getting started so not much content and a little creaky to use. It should improve over time as I get used to it.

My goal is to add links to papers with relevant content to the Black-Litterman model and Asset Allocation in general.

I've started out with a series of papers on Asset classes, and integrating them with the Black-Litterman model. Several of the papers are authored by Thomas Idzorek from Ibbotson.
