+Subject: [PATCH] nvim: handle requests initiates by neovim
+
+Neovim is able to initiate requests to the UI client (via the
+'rpcrequest()') API. Eovim is now able to run a user-defined callback
+function when a request is emitted. A request response is sent back to
+neovim. This is one step to solve #38.
