[Paraview] SEG-Y seismic data loading

[Lester Anderson]

There is an updated version of the code here:
https://github.com/rob-smallshire/segpy

I only have 64 bit Python, and this needs 32 bit PyGtk - anyway the route
for reading the data is certainly there. The one issue we would have is
that seismic data can be both in Time (Z axis) or depth, depending on
whether it has been depth converted.

In terms of attributes to deal with, there could be any number of
components, including velocity, amplitude, density etc. but most people
just view a colour-shaded amplitude image for interpretation. The wiggle
trace is fine at a smaller scale.

As an import, it would be necessary to be able to either read the time of
Z-scale or define manually.
