diff-lcs 1.3

- Updated testing and gem infrastructure.
- Cleaning up documentation.
- Modernizing specs.
- Silence Ruby 2.4 Fixnum deprecation warnings. Fixes #36, #38.
- Ensure test dependencies are loaded. Fixes #33, #34 so that specs can be run
  independently.
- Fix issue #1 with incorrect intuition of patch direction. Tentative fix, but
  the failure cases pass now.

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, gender identity and expression, level of experience,
+nationality, personal appearance, race, religion, or sexual identity and
+orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+  address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at [INSERT EMAIL ADDRESS]. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at [http://contributor-covenant.org/version/1/4][version]

+## Contributing
+
+I value any contribution to Diff::LCS you can provide: a bug report, a feature
+request, or code contributions. Code contributions to Diff::LCS are especially
+<del>welcome</del>encouraged. Because Diff::LCS is a complex codebase, there
+are a few guidelines:
+
+*   Code changes *will not* be accepted without tests. The test suite is
+    written with [RSpec][].
+*   Match my coding style.
+*   Use a thoughtfully-named topic branch that contains your change. Rebase
+    your commits into logical chunks as necessary.
+*   Use [quality commit messages][].
+*   Do not change the version number; when your patch is accepted and a release
+    is made, the version will be updated at that point.
+*   Submit a GitHub pull request with your changes.
+*   New or changed behaviours require appropriate documentation.
+
+### Test Dependencies
+
+Diff::LCS uses Ryan Davis’s [Hoe][] to manage the release process, and it adds
+a number of rake tasks. You will mostly be interested in:
+
+    $ rake
+
+which runs the tests the same way that:
+
+    $ rake spec
+    $ rake travis
+
+will do.
+
+To assist with the installation of the development dependencies, I have
+provided a Gemfile pointing to the (generated) `diff-lcs.gemspec` file. This
+will permit you to do:
+
+    $ bundle install
+
+to get the development dependencies. If you aleady have `hoe` installed, you
+can accomplish the same thing with:
+
+    $ rake newb
+
+This task will install any missing dependencies, run the tests/specs, and
+generate the RDoc.
+
+You can run tests with code coverage analysis by running:
+
+    $ rake spec:coverage
+
+### Workflow
+
+Here's the most direct way to get your work merged into the project:
+
+*   Fork the project.
+*   Clone down your fork (`git clone git://github.com/<username>/diff-lcs.git`).
+*   Create a topic branch to contain your change (`git checkout -b
+    my_awesome_feature`).
+*   Hack away, add tests. Not necessarily in that order.
+*   Make sure everything still passes by running `rake`.
+*   If necessary, rebase your commits into logical chunks, without errors.
+*   Push the branch up (`git push origin my_awesome_feature`).
+*   Create a pull request against halostatue/diff-lcs and describe what your
+    change does and the why you think it should be merged.
+
+### Contributors
+
+*   Austin Ziegler created Diff::LCS.
