VPython 5.72

VPython 5.72 for Windows and Mac (no package for Linux yet):

Corrects a rather serious bug in graphs where plotting (0,.001)
followed by (.001,.001) failed to autoscale correctly.

Also added documentation explaining what objects are used to represent
gdots, gcurves, ghbars, and gvbars:

If you say g = gcurve(), g.gcurve is a curve object used to represent
the gcurve.
If you say g = gdots(), g.dots is a points object used to represent the gdots.
If you say g = gvbars(), g.vbars is a faces object used to represent the vbars.
If you say g = ghbars(), g.hbars is a faces object used to represent the hbars.

It was not possible at this time to work on various other bugs that
have been reported, but they're not forgotten.
