(WX) Viewer example doesn't work in Linux
Expected Behavior
python structure_wingbox.py shows the wingbox as shown in the README.
Current Behavior
After installing with conda as per README, salient part of the console output:

Traceback (most recent call last):

RuntimeError: Xw_Window, given invalid X window
Possible Solution
I found a StackOverflow thread suggesting that in current versions of wxpython you need to use GetId on Linux, not GetHandle. I confirmed the current (pyOCCT) code uses GetHandle, but it does have some Linux-specific code there.
Steps to Reproduce (for bugs)
On Linux (if it matters: Debian testing/unstable, running KDE):
- conda create -n afem
- conda activate afem
- conda install -c conda-forge -c trelau afem
- git clone trelau/AFEM # I use hub so this works
- cd examples/ && python structure_wingbox.py
FWIW I think the underlying issue is in pyOCCT, because I get effectively an analog issue but with python import_step.py. pythonOCC works fine, but they use a Qt viewer on this system by default.
Context
I was trying to run the example.

Can AFEM be used as a general purpose CAD Library?
I have just discovered this project, I have been exploring the documentation and it looks like a great library to use as a base for my little CAD project. Apparently this is designed specifically for Airplane designs but it looks very generic to me. Is there any serious limitation in using this instead of using pyOOCT directly?
My project consist of generating parts from some input parameters, I need a lot of 2D geometry to construct profiles and then build 3D objects doing lofting, extruding, and boolean operations.
Congrats for such a great work.
Thanks in advance.
Intersecting Line with Circle does not work
Intersecting a Line with a Circle must result in zero, one or two intersection points, but in this example it returns zero points where the Line is actually intersecting the circle at two points:
circle = CircleByNormal(Point(0, 0, 0), Direction(0, 0, 1), 20).circle
line = LineByVector(Point(0, 0, 0), Direction(0, 1, 0)).line
points = IntersectCurveCurve(circle, line).points
print(f"points={points}")
Result:
points=[]

add typehints
as it says on the tin -- I think typehints would be a welcome addition.
@trelau would you accept such a PR, since that would basically make the project python>=3.6+?
