A simple REPL bank application

During week 10 at Makers we are practicing the concepts we have covered so far.

The goal of this project is to practice our OOP and TDD skills.

Specification

Requirements

• You should be able to interact with your code via a REPL like IRB or the JavaScript console. (You don't need to implement a command line interface that takes input from STDIN.)
• Deposits, withdrawal.
• Account statement (date, amount, balance) printing.
• Data can be kept in memory (it doesn't need to be stored to a database or anything).

Acceptance criteria

And a deposit of 2000 on 13-01-2012
And a withdrawal of 500 on 14-01-2012
