Trello App Sidebar.py Using DataStore which is not defined #220
Description
The sidebar.py program has a variable in it called DataStore which doesn't seem to be referenced any where else in the tutorial and or any of the requirement documents for this tutorial. The sidebar.py text does not contain any import statements so I don't think it is calling an additional external function.
Can you add more detail to this tutorial? How exactly does the sidebar work? Why is this the only python script in all of the ones in any tutorial that is using a store call in its function definition? It seems very strange to introduce this functionality with very limited detail on what it does in a tutorial that should explain the functionality explicitly.
