Edit/Create set operations allow sets to be created using a formula or editor or edited in a spreadsheet-like fashion.
Edit allows altering an existing set or creating a new one. The editor invoked is either the Xbae edit widget (if installed) or an external editor defined by the GR_EDITOR variable. If the choice of the two is available, a radio button will be present to select the desired editor.
Add a point to a set by copying the currently edited cell and appending it directly afterwards
Delete the current point.
Change the format, precision and column widths of the table.
Refresh the display. This is useful if the set type changes or the number of points changes.
This may only be used to create new sets. See Load & evaluate
