Added PSR-4 compatible autoloader as defined at http://www.php-fig.org/psr/psr-4/.

SurfaceActiveCall.php was split into four files. Each file must contain exactly one PHP class because of the following line in the spec:

> The terminating class name corresponds to a file name ending in .php. The file name MUST match the case of the terminating class name.

Other changes were made to correctly import the library using the autoloader.
