Transformation matrix generator.

Data: matrix

Methods: t = Trans([shift],[center],[axis],[angle],[units]) NOTE: (x,y,z) or (x,y,z,1) treated as Vector, (x,y,z,0) as Coord shift=Vector: translate by this vector (applied last) shift=Coord: translate this coordinate to the origin (applied last) center=Coord: rotate about this coordinate axis=Vector: rotate around line along this direction from center axis=Coord: rotate around line from center to this coordinate angle: amount to rotate in units t(atom) - modify coordinates of an atom t(group) - modify coordinates of a group of atoms t(trans2) - left-multiply another transformation
