YouTrack API wrapper

General classes to communicate with the YouTrack API and execute some commands. Handles login, communication, parses YouTrack responses, and executes commands by project and issue ID. Fetches issues as nice Issue entities.

Usage:

use Guzzle\Http\Client;

require('src/YouTrack/YouTrackCommunicator.php');
require('vendor/autoload.php');

$http = new Client('https://my.youtrack.endpoint');

$api = new \YouTrack\YouTrackCommunicator($http, array(
    'username' => 'your_api_user',
    'password' => 'your_api_password'
));

$myIssue = $api->getIssue('MYPRJ-1');
var_dump($myIssue);

$api->executeCommands($myIssue, ['State', 'Built'], 'I just closed this automagically.');
