[PATCH] gnu: Add opencascade-oce

[Paul Garlick <pgarlick@tourbillion-technology.com>]

* gnu/packages/opencascade.scm: New file
* gnu/local.mk (GNU_SYSTEM_MODULES): Add it
---

The OpenCASCADE library is used for defining 3D geometry.  It can be
incorporated as a build option in other packages.  Examples of such packages
(and the subject domains in which they are used) are Gmsh (mathematics),
IfcOpenShell (architecture) and FreeCAD (engineering).

There are two versions of OpenCASCADE; the upstream version and the community-
maintained version.  OCE is the community-maintained version.
