Replication package of Article: GLL Parsing with Flexible Combinators

This artifact contains the Haskell package `gll` of which aspects have been described and evaluated in the paper "GLL Parsing with Flexible Combinators". The artifact also contains the paper's literal Haskell code which can be tested by running a number of unit-tests. The purpose of the artifact is to enable reproducing the evaluation data of the paper and to confirm the correctness of the implemented algorithms.
