Improved style and style checking.

- Excludes checking of files in /example directories.
- Warns about block imports, which have been removed.
- Checks indenting. Parameters should be indented 2 spaces. See https://docs.scala-lang.org/style/indentation.html#methods-with-numerous-arguments
- Imports should be grouped (java.*, scala.*, other), with a blank line between groups
