Changelog of @hackage/chatter 0.3.0.1

= 0.3.0.1 =

Bumped dependency on base to >= 4.6 (from >= 4) because of Text.Read.readMaybe. This drops support for HP2012, and requires GHC 7.6 or newer.
fixed lots of warnings and added documentation.

= 0.3.0.0 =

Changed the Sentence and TaggedSentence data types to be actual tree structures with real types at the respective layers. ChunkedSentence and ChunkOr were also added to facilitate phrase and clause chunking.
Added a POS Tag data type for Brown corpus tags, and a Chunk type for Chunks as well (in the Brown module, but that's probably not the best place, given that the chunks have nothing to do with the actual Brown corpus.)
Updated the Parsec Examples to use the typed tags/chunks.
Regenerated the defaultTager, it uses the Brown tags now instead of RawTag.

= 0.2.0.1 =

I realized immediately after the 0.2.0.0 release that I broke the defaultTagger by adding the protectTerms function to the LiteralTagger. Things broke because (i) there are bugs in that functionality, which uses run-time assembled regexes, and (ii) the UnambiguousTagger used in the defaultTagger delegates to an instance of the LiteralTagger, which pulled in the (semi-broken) protectTerms function. This has been fixed by replacing the tokenizer when the LiteralTagger is used as an UnambiguousTagger -- the later tager doesn't need the functionality, and it should never have been used there anyway.
Added a bevy of tests to cover the above fix.
Added tests (currently breaking) that exercise the broken bits of the protectTerms function.
