In short, the expected API evolution is as follows:

While in alpha we expect to move forward with it, but may break it.

## Edit json (un)marshaling code
We are auto-generating code for marshaling and unmarshaling json representation
of api objects - this is to improve the overall system performance.

## Making a new API Group
This section is under construction, as we make the tooling completely generic.
At the moment, you'll have to make a new directory under pkg/apis/; copy the
directory structure from pkg/apis/experimental. Add the new group/version to all
directory structure from pkg/apis/extensions. Add the new group/version to all
of the hack/{verify,update}-generated-{deep-copy,conversions,swagger}.sh files
in the appropriate places--it should just require adding your new group/version
to a bash array. You will also need to make sure your new types are imported by
