The default Generics-based ToSample instance now uses Omega type
to productively produce distinct samples. The previous version
was based on lists and hence left-recursive. This means that with
previous versions the default toSamples for [Bool] would return an
infinite list like this:
[[],[False],[False,False],[False,False,False],...
As you can see it would never produce a list with True in it.
Omega handles this and produces a more diverse output:
[[],[False],[False,False],[True],...
This is still not the best possible case, but to do better we need
to use Omega not only in GToSample, but in ToSample as well since
GToSample uses ToSample instances recursively.
- introduce an internal `GToSample` class
- introduce internal functions `defaultSample` and `defaultSamples`
- add default signature for `toSamples` to use Generics
- set default `toSamples` implementation to `defaultSamples`
- remove the `MINIMAL` pragma to avoid warnings for empty instances

Make sure that no information is lost when providing additional
information via docsWith. With the current left-biased implementation of
combineAction, this can happen if the function arguments are in the
wrong order.
When adding extra info using using docsWith, the responses vanished from
the output. This was due to combineAction being left-biased, and
docsWith combining the extra info with the enpoint (in that
order). Flipping combineAction solves this.
