AddRotPoly
==========
```{function}  AddRotPoly( CSX, materialname, prio, normDir, points, RotAxisDir, angle, varargin)
```
Full definition:
```{code-block} matlab
function CSX = AddRotPoly( CSX, materialname, prio, normDir, points, RotAxisDir, angle, varargin)
```

- CSX:          CSX-object created by InitCSX()
- materialname: created by AddMetal() or AddMaterial()
- prio:         priority
- normDir:      normal direction of the polygon,
                e.g. 'x', 'y' or 'z', or numeric 0..2
- points:       two-dimensional coordinates
- RotAxisDir:   direction of the rotational axis
                e.g. 'x', 'y' or 'z', or numeric 0..2
- angle (optional): rotational start/stop angle, default is [0 2pi]

Warning: Polygon has to be defined using Cartesian Coords
         for use with cylindrical mesh, set 'CoordSystem',0

example:

    p(1,1) = 0;  % x-coord point 1
    p(2,1) = 0;  % y-coord point 1
    p(1,2) = 10; % x-coord point 2
    p(2,2) = 20; % y-coord point 2
    % normal direction: z
    CSX = AddRotPoly( CSX, 'PEC', 1, 'z', p , 'y');
