jkriege2 67d23150f2 new: user-interaction tool that shows coordinates of data points near the current mouse position (when mouse is dragged, while mouse button is pressed) 
new: user-interaction tool that measures distances and angles when mouse is dragged, while mouse button is pressed)
update: reworked error indicator base classes and styling settings
update: improved boxplot styling with a separate full-featured pen for the whiskers
