Mode template is missing

[MAKIO135]

Maybe a link to https://github.com/martinleopold/TemplateMode should be added?

Yeah, I built that together with @fjenett for GSOC 2012 (DebugMode). How about integrating this into a new processing-mode-template. Maybe some smaller changes are needed, in naming etc. I'd be happy to do this :)
