Social Networking Kata

Implement a console-based social networking application (similar to Twitter) satisfying the scenarios below.

Scenarios

Posting: Alice can publish messages to a personal timeline

> Alice -> I love the weather today
> Bob -> Damn! We lost!
> Bob -> Good game though.

Reading: Bob can view Alice’s timeline

> Alice
> I love the weather today (5 minutes ago)
> Bob
> Good game though. (1 minute ago)
> Damn! We lost! (2 minutes ago)

Following: Charlie can subscribe to Alice’s and Bob’s timelines, and view an aggregated list of all subscriptions

> Charlie -> I'm in New York today! Anyone wants to have a coffee?
> Charlie follows Alice
> Charlie wall
> Charlie - I'm in New York today! Anyone wants to have a coffee? (2 seconds ago)
> Alice - I love the weather today (5 minutes ago)

> Charlie follows Bob
> Charlie wall
> Charlie - I'm in New York today! Anyone wants to have a coffee? (15 seconds ago)
> Bob - Good game though. (1 minute ago)
> Bob - Damn! We lost! (2 minutes ago)
> Alice - I love the weather today (5 minutes ago)

General requirements

• 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
• 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.
• Use whatever language and frameworks you want. (provide instructions on how to run the application)
• NOTE: "posting:", "reading:", "following:" and "wall:" are not part of the command. All commands start with the user name.

IMPORTANT: Implement the requirements focusing on writing the best code you can produce.

CODE SUBMISSION: Add the code to your own Github account and send us the link.
