Review Comment:
Note for reviewers:
It looks like `artifactMap.get("manifest.properties")` is always populated
as it is validated in the super class(es), so it is guaranteed to be always
present in the map; so it is guaranteed to be never `null`
(`BaseModel#validateArtifactMap()`).
> Provide equals and hashCode for ParserModel and TokenizerModel

> Key: OPENNLP-1412
> URL: https://issues.apache.org/jira/browse/OPENNLP-1412
> Project: OpenNLP
> Issue Type: Improvement
> Components: Parser, Tokenizer
> Affects Versions: 2.1.0
> Reporter: Martin Wiesner
> Assignee: Martin Wiesner
> Priority: Minor
> Fix For: 2.1.1
>
>
> The tests {_}opennlp.tools.tokenize.{*}TokenizerModelTest{*}{_},
> {_}opennlp.tools.parser.chunking.{_}{*}_ParserTest_{*}, and
> {_}opennlp.tools.parser.treeinsert.{_}{*}_ParserTest_{*} signal by TODOs that
> no actual assertions are made to check whether (de-)serialized Model
> instances are correctly read in again.
> In other words: Those (Tokenizer/Parser) models lacks a valid equals/hashCode
> implementation by which one could verify a valid state (=equality) after
> (de-)serialization has occurred.
> Aim:
> * Provide an improved implementation of the related "Model" classes.
> * Remove existing TODOs in _TokenizerModelTest_ and _ParserTest_
> * Improve the three test classes with further test assertions.
