relationship(), to eliminate confusion over the relational
algebra term. relation() however will remain available
in equal capacity for the foreseeable future. [ticket:1740]
- added READMEs to all examples in each __init__.py and added to sphinx documentation
- added versioning example
- removed vertical/vertical.py, the dictlikes are more straightforward
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.
