Serge Bazanski 2efb698d22 *: add default.nix/readTree
This makes all Nix files addressable from root by file path.

For instance, if a file is located in //foo/bar:baz.nix containing:

    { pkgs, ... }:

    pkgs.stdenv.mkDerivation {
      pname = "foo";
      # ...
    }

You can then do:

    nix-build -A foo.bar.baz

All nix files loaded this way must be a function taking a 'config'
attrset - see nix/readTree.nix for more information. Currently the
config attrset contains the following fields:

 - hscloud: the root of the hscloud repository itself, which allows
            for traversal via readTree (eg. hscloud.foo.bar.baz)
 - pkgs: nixpkgs
 - pkgsSrc: nixpkgs souce/channel, useful to load NixOS modules.
 - lib, stdenv: lib and stdenv from pkgs.
