/**
* Example to send single push notifications.
*
* For easy setup we use the SQLite dataprovider and set the database file
* located in the same directory as this script.
*
* First you should open PNTestClient.html in your browser and click the
* [Subscribe] button to create a valis subscription in your database.
*
* Needed steps to send notification to all subscriptions stored in our database:
* 1. Create and init dataprovider for database containing at least one valid subscription
* 2. Set our VAPID keys (rename MyVapid.php.org to MyVapid.php ans set your own keys)
* 3. Create and set the payload
* 4. manuelly step through the Subscriptions...
* 5. .. and push each of the notification by single call
*
* After the notification was pushed, a summary and/or a detailed log can be
* retrieved from the server
*
* If you want to log several events or errors, you can pass any PSR-3 compliant
* logger of your choice to the PNDataProvider- and PNServer-object.
