It's basically going to be like this for each polygon inside that 1D array
of polygons:
[N, i1, i2, i3, i4, i5...]
where N gives the number of indices for that polygon. It'd then be
followed by more definitions until you reach the end of the array.
But looking at it, it does seem slightly tricky to use as you'll have to
go through every single polygon skipping the indices to total up how many
triangles each polygon uses (based on numtriangles = numindices-2).
I'd advise you to write a C++ command to get the information because a)
using a script to do this willalmost certainly be pretty slow, and b)
there's a GetTriangleCount() method in the C++ CGeometryAccessor class
which does exactly what you want already.
