Simple todo application with pagination

In first chapter we've implemented a simple todo application. It has one limitation, if our task list would grow big enough then view would be slow.

• We will generate 20000 tasks
• We will allow max 50 tasks at any given time
• We will implement pagination so we can navigate to see all of the data in the store

Whole source code can be found as example todo_2

Goals

• Describe StoreView in details
• Implement pagination for the list of tasks
