WIP Extract configuration logic

TODO
- Readme module.
- iterationFailures unused?
- remove check failure in next commit?
- check if PException was caught on next iteration
- configured shouldn't catch PException
- vanilla `parameterize` docs, and other configuration docs
- merge iterator -> state (vanilla & configured)

Improves performance of unconfigured parameterize, and greatly simplifies core logic
configuration may be dropped later
