Expand on NMG tutorial

This is a follow-on of http://www.google-melange.com/gci/task/view/google/gci2014/5546966268248064
The write-up is basic, but is a little opaque in its current form. We'd like to improve it with a simple understandable example, like creating a box and then putting a hole through the box.
Update the tutorial on http://brlcad.org/wiki/NMG to have the example 1) show steps for creating a box or other simple shape, 2) show that shape as an rt and wireframe rendering, 3) show additional steps for making a hole through the shape, and 4) show that shape as an rt and wireframe rendering.References:
