add/remove relations

[jobrienski]

I added a function called relate to add or remove a relation to your code. Not that good at github, so here is the function:

/**
 *
 * Used to add or remove a relation to a parse.com object
 *
 * @param array $args - argument hash:
 *
 * className: string of className
 * objectId: the objectId of the object you want to update
 * add: boolean
 * columnName: the column name of the relation
 * relationClassName: the classname of the relation you want to add
 * relationObjectId: the objectId of the related object
 */
       public function relate($args){
                $params = array(
                        'url' => $args['className'].'/'.$args['objectId'],
                        'method' => 'PUT'
                );

                $objects = array(
                        "__type" => "Pointer",
                        "className" => $args['relationClassName'],
                        "objectId" => $args['relationObjectId']
                );

                $relation = array(
                        $args['columnName'] => array(
                                                "__op" =>
                                                ($args['add'] ? "Add" : "Remove") . "Relation",
                                                "objects" => array($objects)
                                        )
                );


                $params['payload'] = $relation;

                $return = $this->request($params);

                return $this->checkResponse($return,'200');
        }

In the interest of full disclosure, I haven't thoroughly tested this. "Add" seems to work, haven't tested "Remove" at all.

Thanks! I'll put this in the new version, it will have some tests in there.
