First stable release

This is the first stable release, which basically means it's ready to be used in production.

Move to static method

Moved to static method for transforming.

Since only one method is used when transforming data, it's not necessary to create a new Mantle object every time data has to be transformed. Now, there is only one static method that has to be used:

use Mantle\Mantle;

$object = Mantle::transform($data, $class);

Initial release
