Returns a function that looks in a specified path relative to the current
directory, and returns all .js modules in it (recursively).

####Example:

    var importRoutes = keystone.importer(__dirname);

    var routes = {
        site: importRoutes('./site'),
        api: importRoutes('./api')
    };

@param {String} rel__dirname
