WEDGE_GRID <br> Grid Points Within the Unit Wedge
</h1>
<hr>
<p>
<b>WEDGE_GRID</b>
is a C++ library which
generates a grid of points
over the interior of the unit wedge in 3D.
</p>
<p>
The interior of the unit wedge in 3D is defined by the constraints:
<pre>
0 <= X
0 <= Y
X + Y <= 1
-1 <= Z <= +1
</pre>
