Inbuilt method for EllipticCylinder (Python API)

Hi all,

Is there a way to access the `EllipticCylinder` function (I can see it here ) from the python interface? Something along the following lines

```
from netgen.csg import *
Cylinder()
```
I am able to a lot of the primitives, specifically both `OrthoBrick` and `Cylinder` but not `EllipticCylinder`. Am I missing anything ?

I just did a brief check and found out that a binding for `EllipticCylinder` is missing (in the file below). Am I missing something here? I can access all other functions (`Cone`, `EllipticCone` etc.)

I think you can use an elliptic cone with ratio r=1 instead.
