Summary: iges-g crash

Initial Comment:
On using the -n option (as suggested by iges-g), iges-g will crash during conversion (the initial phase, detecting all objects, succeeds)
On using the -t option, iges-g also crashes, but this time an error message appears, saying that a curve was not closed.

Message:
This is unfortunate but not unexpected.  There are a variety of generalized
spline-surface imports that can be represented with IGES that our iges-g
cannot understand (particularly when they're not solid geometry).

Work is underway now on a new step-g importer that will be a recommended
path through STEP instead of via IGES import.  As that converter comes
on-line, we can then focus on updating older tools (including iges-g) to
use the new NURBS boundary representation primitive that is in development
now (and nearing completion).
