Right Angular Wedge

A right angular wedge can be constructed using C++ or some simple text:

:volu wedge TRAP
 30 // half height along z in mm
 40 // half height of the base (along y) in mm
 50 // half length of the long side of the base in mm
 20 // half length of the short side of the base in mm
 G4_W // material

git clone https://github.com/jintonic/geant4
