RICH: definition of a supermodule.CSUP: riCh SUPermodule
CSUP describe the rectangular front surface of a supermodule. The orientation in space is defined by the three vectors x0,ex=xvec/||xvec||, ey=yvec/||yvec||. The norm ||xvec|| and ||yvec|| defining the outer dimensions of the rectangle. The supermodule is devide in matrice like cells. This is done by setting nx=12, ny=36, xdiv=ydiv=36 mm.
