Lots of fixes to the code examples to specify imports explicitly.
Explicit imports make it easier for users to understand the examples.
Additionally a lot of the examples were fixed to work with the changes in the
0.5.x code base. One small correction to the Case expression. Thanks a bunch
to Adam Lowry! Fixes #717.
