Finished the basic required functionality.

Consists of the basic client-server code. Client gets location info,
connects to the server, "checks-in" to the server (basically sends its
data to the server to print).

Server gets data from the client and prints it on the screen.

Uses the TCP protocol for communication between the client and the
server. The communication data is in the JSON format for easier parsing
on either side.

The application adapts well to Android devices of any screen size.
