Notes

• Application must use the console for input and output;

• User submits commands to the application:

  • posting: <user name> -> <message>
  • reading: <user name>
  • following: <user name> follows <another user>
  • wall: <user name> wall
  • mentions: <user name> mentions
  • DMs: <user name> messages

• Don't worry about handling any exceptions or invalid commands.

• Assume that the user will always type the correct commands.

• Just focus on the sunny day scenarios.

• NOTE: "posting:", "reading:", "following:", "wall:", "mentions:" and "DMs:" are not part of the command. All commands start with the user name.
