/*
* This class is used to collect usage statistics of all SimpleServer users. To fulfill
* this task it is necessary to send a short request to our server when starting SimpleServer
* and then an even shorter one every minute it runs. This only uses a negligible amount of
* computational power and bandwidth and should not impair your gaming experience in any way.
*
* In order to preserve your privacy the gathered data is stored anonymously which means
* your server is only identified by your random map seed and the first two bytes of your
* IP address (if your IP is 135.42.67.166 only 135.42 is stored).
*
* The collected data consists of the following information:
* SimpleServer version
* Server options: alternativeJar, onlineMode, customAuth, maxPlayers
* Server statistics: number of registered players, total playing hours
*
* Your data will not be used in any evil plots to take over the world. Before publishing
* it in any way your server identifier (see above) is removed to guarantee complete anonymity.
*
* If you are paranoid or just don't want to support the developers of SimpleServer you can turn
* this feature off by adding the property "disableStatistics" with value "true" to your
* simpleserver.proeprties file.
