Adding functionality

[dsbw]

I wanted to add some features not built-in to infix, so I did the following:

1. Defined the routines I wanted to use:

(defn max [a, b] (Math/max a, b))
(defn min [a, b] (Math/min a, b))

2. Created a map with those routines:

(def obz-fns {:max max
              :min min})

3. Merged them into the existing routines:

(def all-fns (merge base-env obz-fns))

4. I then use my all-fns when calling from-string:

((from-string [] (merge all-fns local-vars)  "min(a,b)")))

This seems to be pretty trauma free. Just wondering if I should beware of any particular dangers.

That is usage exactly as intended
