Numerical Analysis Category Added

I have added a numerical analysis and scientific computing category to the site because one of my best friends just enrolled for his mathematics graduate degree at the University of Minnesota, and his two of his first semester class are Solution Of Continuous Models and Numerical Linear Algebra. I took both of these at the Fulton School of Engineering at ASU, so when we work on managed code stuff I am going to throw it up here so I don’t have to do it twice again :)
