Changed RuntimeError('Unexpectednumberofedges',11) to
RuntimeError('Unknownerrorhasoccurred.') in the speedup
that does surface-surface intersection
(35ab5d5).
The old error message was a “copy-paste” artifact from the
basic_interior_combine() Python helper.
Removed a flag (-march=native) from the build process for the
bezier._speedup extension module
(e739429).
Using the flag caused the manylinux wheels to be “broken”
(see #98).
