Hi! The contributions are much appreciated!

We do want these updates, but probably want to organize them a little differently. The app name is still SketchUp.app, so according to our naming conventions, the Cask is still named sketchup.app. (There is a script to generate the name at ./developer/bin/cask_namer, and a document at CASK_NAMING_REFERENCE.md.

The Pro version is an alternate version of the same app, so it should be submitted to the versions repo.

The SketchUpViewer.app submission is a welcome addition. However, it should be renamed to sketchupviewer.rb with a first line reading

class Sketchupviewer < Cask

The comments on sketchup-pro also apply to these two casks. Would you mind making the changes?

@rolandwalker I noticed eclipse follows my original commit pattern of sketchup-make + sketchup-pro as eclipse-ide, eclipse-java, eclipse-jee, eclipse-platform
old pattern, or is this any different?

@jconley, good eye, old pattern. Sorry if you copied from that. We are trying to make things more systematic/predictable.
