Improve flexibility

This will make it easier to run the parser in a multi-stage
setup without sacrificing the standalone setups.

Modified comp to extract the location of parsed things.

I expose the parts of the Input, Parsing and Failure objects
to customize error handling.

Parsing and Failure objects have a default printer now.
