States Within the Edit Process

In this tutorial, the user will invoke MGED on a file called ``prim.g''; attach a display manager; explore the various MGED states; and finally, exit MGED. A MGED database has a treelike structure. The leaves are the individual solids, and the other nodes are groupings of those solids. The solid editing functions are concerned with defining and modifying the leaves, and the object editing functions operate on groups, which are Boolean combinations of solids. One useful mental model is to envision solid editing as operating directly on a leaf and object editing as operating on the arc connecting a pair of nodes. The object edit will affect everything below the selected arc (this is why there is an additional state transition when object editing).
