EMSegmenter in Slicer4

TODO

• untie KWWidgets from EMSegment base
• untie KWWidgets from EMSegment commandline tool
• create EMSegment4 as an extension for Slicer4
  • include the commandline tool in the extension (Problem: infrastructure is not ready yet)
• Merge old EMSegment4 and the new extension all in Slicer3 repository
• introduce Slicer Common Interface (SCI) which holds functionality which is different between Slicer3 and Slicer4 but provides the same API for both
  • provide EMSegment3 functionality in the SCI
  • provide EMSegment4 functionality in the SCI (work in progress)
• update EMSegment4 Qt Gui
• provide nightly extension builds

Slicer Common Interface (SCI)

The Slicer Common Interface is a class with a unified API for Slicer3 and Slicer4 which includes functionality which has to be realized differently among the two Slicer versions.
