* Initialize phery by scanning the target class for response methods.

*
* An data-remote method defined on the client side should have a corresponding response method
* with the same name prefixed by "ph_". Usage example:
*
* View:
* <button data-remote="testmethod" >Call ph_testmethod in target class</button>
* or equivalent
* <?php echo phery::link_to('Call ajax_testmethod in target class', 'testmethod', array('tag' => 'button')); ?>
*
* Controller:
* public function before() {
* parent::before();
* Pheryajax::init($this); // <-- This init function looks for response method "phery_testmethod" in the controller itself ($this)
* }
*
* public function phery_testmethod($data = NULL) { // <-- "ajax_testmethod" corresponding to client side "testmethod"
* return PheryResponse::factory()->alert('Hello from ph_testmethod!');
* }
*
* @param $target_class where to look for methods that will be triggered by ajax calls
* @param $phery_callbacks
