It is a rain day, so from 6:30 AM to 8 AM, some initial centroid work was done.
A break is now required, so here is some non-functional code :-)

The task is so easy to understand, yet so hard for this slow amateur programmer to code... :-)

The non functional draft node can be copied to the nodeeditor extension folder, to add it to the construct2 menu.
The node may then be selected from the construct2 menu, and the node is displayed, but does not function further.

Bogging down again, so 2nd break...got to go do some work...
