Use Std.Core in merlin and tuareg's toplevel within emacs

Using Core.Std in Emacs
=======================

merlin
------
When you want to use external libraries installed with opam (findlib?).
You could do it by using `merlin-use` command, it will prompt you for a package name.
For example, we need to use Std.Core:

M-x merlin-use
Package to use: Core

toplevel
--------
This is the same as running OCaml's toplevel (ocaml). We need to use `topfind` module
which provide 'require' directive to load external libraries to the current toplevel.

For example:
#use "topfind";;
#camlp4o;;
#thread;;
#require "core.top";;
open Core.Std;;
