Minimum PHP-Version

[etenzy]

Is it possible to set the minimum PHP-Version down to 5.4.0?

I'm bound to use PHP 5.4.24 and tested the package with this version without any issues.

@mroedel Thanks for suggestion.

Yes it seems not using any of the php5.5 features in the code. Except the document uses the new ::class class name resolution. We will modify the doc, and bind it to php5.4.

Thanks!
