0.2 - Implement Models and Persistence

This is the first usable version of Agile Data.

You should be able to define your models:

class Model_User extends \atk4\data\Model {
    protected $table = 'user';
    function init() {
        parent::init();
        $this->addField('name');
        $this->addField('surname');
    }

and then use them:

$m = new Model_User($db);

$m->load(1);
$m['name'] = 'John';
$m->save();

This implementation contains:

• Active Record (array access) implementation
• Driver implementation Array and SQL (on top of DSQL)
• Record field type bi-directional mapping (boolean, date, enum, json)
• Mechanic for tracking field changes (original values, dirty etc)
• Ability to move field from one persistence driver to another
