3D plots can share view angles
2+
------------------------------
3+
4+
3D plots can now share the same view angles, so that when you rotate one plot
5+
the other plots also rotate. This can be done with the *shareview* keyword
6+
when adding an axes, or by using the *ax1.shareview(ax2)* method of
7+
existing 3D axes.
