parse-csv returns a sequence of vectors. The "functional way" of traversing
a sequence is using map:
(ns foo
(:gen-class)
(:use clojure-csv.core))
(defn process-file
"Process csv file and prints first item in every row"
[file-name]
(let [data (slurp file-name)
rows (parse-csv data)]
(dorun (map #(println (first %)) rows))))
(defn -main [& args]
(process-file "resultset.csv"))
