//the sub-containers
//This event is fired for each annotation
//Toggles the Grouping feature for all the containers

//before clicking on this button
//Note that after you disable the grouping you can select and change
//individual objects belonging to a group. When you re-enable
//the grouping, the objects act as a group again.
