* A demo based on GraphEdX that demonstrates a simple way of allowing the user
* to edit cells inside groups or the groups themselves. NB: in order to have the
* edit button displayed in the top layer (not shadowed by child cells), we need
* to display them on the border away from the child cells. To do that, we
* assume we groups have larger bounds than the union of their child cells, a
* feauture implemented in GraphEdX in the group method.
*
* Remark: using a click system rather than this button system wouldn't work
* because the click count is already used to traverse the cell selection.
