Brep Components Disabled

[dcascaval]

Components that call functions in parallel on Rhino.Geometry.Brep can cause startup errors in certain situations, causing a System.AccessViolationException to be thrown in external code (in RhinoCommon.dll. This not only causes Grasshopper to crash, but nukes the whole Rhino application immediately, which is unacceptable under any circumstances. While a bug report has been submitted to McNeel, this seems like an underlying issue with race conditions in the Brep class in general.

Of course, meshes provide a more performant alternative to Breps for most Grasshopper use-cases, so this (hopefully!) does not represent a large loss of functionality.
