MDC-104 Step 7 - code mismatch with codelab instructions

[thevarunshah]

The following two lines which need to be replaced in the _ShrineAppState class are actually in the ShrineApp class in the code. Documentation is correct, code needs to be updated so people don't copy/paste into the wrong class and get confused.

// TODO: Add variable for selected Category (104)
// TODO: Add a callback when a Category is tapped (104)

Looked at the starter branch for MDC-104 and the problem can't be fixed in code. The documentation needs to highlight that when you convert ShrineApp to a StatefulWidget, the comments stay in the ShrineApp class but the documentation has them in the _ShrineAppState class. If someone isn't paying attention to the class name while trying the codelabs, they can easily miss this detail.

Thanks for reporting this! I've removed the todos you referenced because they are confusing! If this is not what you were thinking, let me know and we can take another look.
