Grid Points Within the Unit Wedge

**WEDGE_GRID**
is a Python library which
generates a grid of points
over the interior of the unit wedge in 3D.

The interior of the unit wedge in 3D is defined by the constraints:

0 <= X 0 <= Y X + Y <= 1 -1 <= Z <= +1

**WEDGE_GRID** is available in
a C version and
a C++ version and
a FORTRAN90 version and
a MATLAB version and
a Python version
