Allows grouping / ungrouping of objects.
After installation the plugin will show up in;
Edit->Group

1. Select two of more objects on the screen, click on 'Group' from the menu, all those items will now be selected at the same time by just clicking on one item of that group.
2. Select a group by clicking on one member of that group then click, 'UnGroup' from the menu to explode the group.
3. The group name will appear in the 'Tag' field of every entity within a group.
