In the master branche this numeric is still more of an extension to numpy
than a replacement. Indeed, in future this is going to change, as is
already the case in the "nocache" and "sane" branches.
Actually in the current case Orthotropic need to be able to handle E, G and
nu as functions, so it should use function.* instead of numpy/numeric. I
happen to know that this modification is already available so
@wijnandhoitinga could you push this to your repository to make it part of
this request?
But thanks for the quality control!
