Collection of 2D Vector Operations.

Usage

 (ns vector-ops
   (:refer-clojure :exclude [+ - * =])
   (:use (clojure.contrib.generic [arithmetic :only [+ - *]]
                                  [comparison :only [=]]))
   (:use [vector-2d.core] :reload-all))

 (let [u (vector-2d 1 1)
       v (vector-2d 2 2)] 
   (+ u v))

 (let [guard-pos (vector-2d 1 3)
       guard-facing (vector-2d 1 1)
       hero-pos (vector-2d 3 2)] 
   (if (in-view-cone? guard-pos guard-facing 80 hero-pos)
     "Guard Can See!!"
