Reconstructing traject to get better error messages and ordering.
Introduce a new node and traject abstraction.
Simple traject is working.
Logic fix and more tests.
Remove unused code sketch.
converter now has a weight, where int goes before str.
Some test failures that fail right now. We could implement
backtracking, or simply make this eager.
Morepath being greedy here is official.
A few more tests that clarify how things work.
Path related tests. Need to refactor though.
Add tests for model registration. But consider moving model
registration code into another module.
Implement a non-namespace aware form of parse_path and create_path,
much simpler.
use new parse_path in new traject.
A few notes.
We now got neotraject integrated into the rest.
Also fix base so that it works with neotraject; base argument is
now always passed in optionally using mapply.
Rename neotraject back to traject.
