Hi there 👋

This is an start for #10 allowing you to run test in a CI environment like Travis. There is a successful build of this branch right here.

I had to change a couple of things to get this done. Details below.

What has been done

• Dropped support for PHP 5.6 since you were already using the return types
• Listed the Zend Framework dependencies used in composer.json so you can develop and test this module without integrating it in a complete ZF application.
• Created a Travis build matrix/pipeline that will test the module across all PHP 7 versions
• Created two tests who assert the default config, so no actual behavioral tests

How to test

• Checkout PR
• Run composer update
• Acknowledge that PHPunit is installed
• Run ./vendor/bin/phpunit and acknowledge that the tests run
