adds the basic skeleton of our slider

It is a slider made with ascii characters it is bounded between one and
nine has two buttons and when it has focus can be controlled with arrow
keys.
Fixes the === and adds the forEach loop.

We add the === to our integer compares and utilize the angular.forEach
function to loop through the slider array.
