Composer dependency

[adrian-tilita]

If i try to use to library outside a symfony environment like this:

{
    "require": {
        "leaseweb/api-caller-bundle": "1.2.6"
    }
}

and using the code:

<?php
require_once 'vendor/autoload.php';

use Lsw\ApiCallerBundle\Caller\LoggingApiCaller;
use Lsw\ApiCallerBundle\Call\HttpPostJson;

$caller = new LoggingApiCaller([]);
$curlCall = new HttpPostJson(
    'http://myurl.com',
    ['foo' => 'bar']
);

var_dump(array(
    'body' => $caller->call($curlCall),
    'status' => $caller->getLastStatus()
));

I end up with the following dependency error:

Error: Class 'Doctrine\Common\Util\Inflector' not found in [mypath]/vendor/leaseweb/api-caller-bundle/Lsw/ApiCallerBundle/Helper/Curl.php on line 38

Unfortunately, it is tied to Utils, not separate Inflector lib.

The fix is simple, just include "doctrine/common" in the library composer requirements.
Should I make a PR.
