Restructure mysimd.hpp and add support for AVX512. Changes include
- Move mysimd.hpp to ngsimd.hpp
- Expose ngsimd.hpp to NGSolve
- New namespace ngsimd
- Second template parameter (width) for SIMD class, default to the
largest width available
- Avoid raw avx register types in the interface, use SIMD<> instead
Netgen mesh generator
NETGEN is an automatic 3d tetrahedral mesh generator. It accepts input from constructive solid geometry (CSG) or boundary representation (BRep) from STL file format. The connection to a geometry kernel allows the handling of IGES and STEP files. NETGEN contains modules for mesh optimization and hierarchical mesh refinement. Netgen 6.x supports scripting via a Python interface. Netgen is open source based on the LGPL license. It is available for Unix/Linux, Windows, and OSX.
