ender.prototype = ender.fn = Ender.prototype

**ender.prototype** - Set `ender.prototype` to these so that `$('a') instanceof ender` will be `true` and so that if you add to the fn object like `ender.fn.example = 47` then it will map to the prototype and make `ender.fn.example === ender.prototype.example` be `true`.

**_select** - Make it so the default `_select` function can handle `$('')` and other falsey inputs without throwing a DOM exception 12 error.
