This is a sub-task of issue #21.

I'll be starting a new project from scratch and building the following:

• [x] Initialise the project
• [x] Table View for iPhone
• [x] List Dummy data in Table View
• [x] Add/Edit/Delete Tasks from Table View
• [x] Store the data in an appropriate format in the model
