%SUMMARY ROT2: 2D rotational transformer
%DESCRIPTION {ROT2} implements a 2D rotational transformation in terms
%DESCRIPTION of a set of transformers. A flow expressed in the X-Y
%DESCRIPTION coordinates is transformed by ROT2 into the coordinates
%DESCRIPTION of x-y. The corresponding (energy conserving) effort
%DESCRIPTION transformation is implied.
%DESCRIPTION Ports X and Y correspond to the old coordinate system
%DESCRIPTION Ports x and y correspond to the new coordinate system
%DESCRIPTION Port theta is the angle of XY with respect to xy.
