Make highlighting optional ? #78
Description
The new highlighting functionality allows single picking a point/bin and puts a magenta border around it. Particularly for the Histogram2D artist, the other bins become currently grayed-out. To "unhighlight" the point/bin, the user must press the Escape key, which may not be intuitive to all.
This issue addresses the possibility of making the highlight feature optional via initialization argument, allowing other developers to choose whether they actually make usage of it or not.
