(use 'clojure.contrib.generic.functor)
(println (fmap testFunc {:a 1 :b 2 :c 3}))
Prints: {:c 6, :b 4, :a 2}
fmap maps a function on the values in a data structure, returning an
equivalent data structure containing the function results. This is
different from map that applies a function to a sequence and returns
another sequence.
