REVISION SUMMARY
  The marker (worksheetInfoElement) is an element, which can show curve values at specific positions of the curve.
  
  F6513605: 2018-12-24 23-49-54.flv <https://phabricator.kde.org/F6513605>
  
  What does not work (Work in progress):
  
  - deleting marker does not delete the custompoint and the textlabel
  - loading projectfile does not work, because in assignCurve() curve.path() returns only the name and not the path which was saved in the marker (worksheetInfoElement) element. Don't know why
  - the custompoint is always behind the marker connection line. Don't know how to change that behaviour
  - setting visible does not work. Don't know why setting does not work.

REPOSITORY
  R262 LabPlot
