Getting TokenMismatchException Error

I'm running through this tutorial http://laravelblog.com/how-to-create-a-basic-contact-form-validate-input-and-send-mail

Not sure what I am doing that is throwing this error as I followed his directions almost exactly. My controller name is different but I've accounted for that. Here is my controller

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Http\Requests;

class contact extends Controller
{
    // This function will show the view
    public function showForm()
    {
        return view('pages.contact');
    }

    public function handleFormPost()
    {
        $input = Input::only('name', 'email', 'msg');

        $validator = Validator::make($input,
            array(
                'name' => 'required',
                'email' => 'required|email',
                'msg' => 'required',
            )
        );

        if ($validator->fails())
        {
            return Redirect::to('contactform')->with('errors', $validator->messages);
        }

    }
}

Here is my routes.php

<?php

/*
|--------------------------------------------------------------------------
| Application Routes
|--------------------------------------------------------------------------
|
| Here is where you can register all of the routes for an application.
| It's a breeze. Simply tell Laravel the URIs it should respond to
| and give it the controller to call when that URI is requested.
|
*/

Route::get('/', function () {
    return view('pages.home');
});

Route::get('request', 'controller@request');
//Route::get('contact', 'controller@contact');
Route::get('contact', 'contact@showform');
Route::post('contact', 'contact@handleFormPost');

Here is my contact.blade.php

@extends("layout")

@section("content")
<h1>Contact</h1>

            </div>
        </div>
    </form>
</div>

@stop

What can I do to fix this and get moving again?

EDIT: Adding in {{ csrf_field() }} seems to get around the first error but doing so creates a new error "Fatal error: Class 'App\Http\Controllers\Input' not found." I am not familiar with csrf_field, so I did not know I needed this controller or what to put in it
