Added a handler for post http requests.
Added sample config file that will be used later.
Rewritten the http handler.
http handler now uses HttpUrlConnection instead of the deprecated HttpClient.
General refactoring and documentation.
Minor changes to PostHandler.
The connection currently blocks on sending post data.
Basic networking class is working.
Refactoring in the POST handler added a GET requests handler.
POST now seems to work.
Both POST and GET work now.
Added timeouts for all read and connect operations to avoid blocking.
