Feature Request: Code Formatting as Command Line tool

[VolkmarR]

From the discussion in Issue #552 I noticed, that @fforay is currently working on the "format document" process.

Since there is work happening in this area, I wanna ask, if it would be possible to expose the same functionality as a command line tool, so that it can be used for the following use cases:

• Re-format a complete solution
• Re-format changed files as part of the git commit process

Especially the second use case would be very useful because it would eliminates the need, that the developers have to reformat the code before committing.

There is a similar tool for c# called CleanupCode.
