I don't want to generally enable the tracker but need activate it by middleware or command.

The "use_middleware" seems not to be implemented.

How to start it?
use Tracker;
Tracker::currentSession();

Doesn't work!!

It only works with 'enabled' => true, in the config for each request.

adapt_boost_variant.hpp is a good start, but it isn't enough to understand the concept.

E.g., what is subtype_cast_impl for? How Am I supposed to say that a reference to super-type should be cast to a reference to a sub-type?

It would be valuable to have some documentation for the special schema YAML file that we drop into your project after you first set up your app to talk to a TestTrack server.
