Console input handled by multiple classes

[akshaysmurthy]

The Alien and ExportAlienDetails classes are both handling console input. This is not so good in two ways -

• Unnecessary responsibilities for the two classes
• If you have to change the input method to a file instead of the console, then changes will be required in multiple places

hmm yes :) I should have kept it Initially I had planned like that During course of developing somewhere I left it :(

A new module 'inputHandler' has been added which manages console input Please checkout
