Add minor things
Convex Optimization Kit

Added Gauss Seidel System solver (UNTESTED YET)
Added SPD matrix inversion (2% speedup, loose in stability)

Optimization Support:
Newton Solver, Conjugate Gradient for Quadratics
Supports Affine,Quadratic functions, Quadratic Penalty for Affine,
Dedicaded Quadtratic minimization with affine inequality constraints (fastest so far)
Optimization Testing
