Accept Header Service Provider

This serivce provider enables you to easily filter routes based on accept headers.

To use it, simply do the following:

<?php

use Pff\ServiceProvider\AcceptHeaderServiceProvider\AcceptHeaderServiceProvider;

$app->register(new AcceptHeaderServiceProvider());

$app->get('/test', function($accept_header) {
    if ($accept_header == 'application/ven.test.v1+json')
        $cont = json_encode(array('content' => 'hello'));
    else
        $cont = '<content>hello</content>';

    return new Response($cont, 200, array('Content-Type' => $accept_header));
})->accept(array('application/ven.test.v1+json', 'application/ven.test.v1+xml'));


$app->get('/test', function($accept_header) {
    if ($accept_header == 'application/ven.test.v2+json')
        $cont = json_encode(array('content' => 'hiya'));
    else
        $cont = '<content>hiya</content>';

    return new Response($cont, 200, array('Content-Type' => $accept_header));
})->accept(array('application/ven.test.v2+json', 'application/ven.test.v2+xml'));

Now a request with accept headers including application/ven.test.v1+json and application/ven.test.v1+xml will be handled by the first route, and requests with accept headers including application/ven.test.v2+json and application/ven.test.v2+xml will be routed to the second.
