    Checkstyle configuration that checks the Google coding conventions from Google Java Style
    that can be found at https://google.github.io/styleguide/javaguide.html

    Checkstyle is very configurable. Be sure to read the documentation at
    http://checkstyle.org (or in your downloaded distribution).

    To completely disable a check, just comment it out or delete it from the file.
    To suppress certain violations please review suppression filters.

<!--  This custom rule exists because "Indentation" has some gaps.
             In particular, while it flags if a line isn't indented far
             enough, it often doesn't flag if a line is indented too far.
             While "Indentation" has the "forceStrictCondition" option which
             would handle that, it also is too strict in other ways such
             that one can't both satisfy the IntelliJ auto-formatter and
             this rule at the same time.
             So this custom rule simply asserts that each line isn't indented
             more than 16 spaces (4 regular indents or 2 continuation indents)
             further than the one above it, so to take care of the main concern
             "forceStrictCondition" would have handled but without the other effects.  -->
