Preliminary flycheck support for Clojure using Cider and Eastwood

;;; clj-fly.el --- Flycheck: Clojure support -*- lexical-binding: t; -*-
;;; Commentary:
;;; So far, this only invokes eastwood. It works best if flycheck-pos-tip is used, so as not to clash with Cider doc messages.
;;; Code:
(require 'cider-client)
(require 'flycheck)
