Jon Schlueter found the divide by zero, and DrDaemonEye pointed me to
some rounding issues.  ntpshmvis was rounding timespecs to 5 digits after
the decimal point, which is a problem when trying to display data that
has 9 digits after the decimal point.

I applied Jon's patch, changed rounding of 5 to 9, and used Numpy float128
to preserve the full precision of the inputs.  Not being a Python guy
it may be still not quite right, but it seems to work for me, based on 
very limited testing.

So pull and go forth testing.
