Util Docs

To generate the user guide website locally, cd into the util directory and run the following commands.

$ ./sbt util-doc/make-site
$ open doc/target/site/index.html

To publish a new version of the util docs to GitHub Pages:

1. Make sure SBT sees the current version as the release version of
   Util (and not the SNAPSHOT version) by running from the master branch.
2. `cd` into the `util` directory.
3. Execute the script `pushsite.bash`.
