attoparsec-run

Conveniently run Attoparsec parsers.

This package fixes a number of problems with the API that Attoparsec provides for running parsers. The difficulties stem from the that that Attoparsec's IResult type encompasses three situations: When parsing has succeeded, when parsing has failed, and when parsing is awaiting further input. This is insufficient to describe situations in which we know we are dealing with a subset of these three cases. We address this by introducing two smaller types: FinalResult and ParseError.
