Changed formatting of README

1. Corrected markdown errors so list formatting and bolded text now appear as intended. 
2. As it is this material is too long for the README. It belongs in the Wiki, as do all extended discussion of implementation or the underlying theory. The README should contain a brief overview, a QuickStart guide, more detailed notes on installation, and a reference to the Wiki.
