WIP: Create Basic CLIs

[wilson-ben]

Adding C++ CLIs with functionality. They have not been implemented within Surface Toolbox yet.

I still need to update XML files and extension settings.

i posted few comments.

It may also worth looking into implementing CLI using approach like this one:

• https://github.com/Slicer/Slicer/blob/master/Base/QTCLI/Testing/PyCLIModule4Test.py
• https://github.com/Slicer/Slicer/blob/master/Base/QTCLI/Testing/PyCLIModule4Test.xml

We could even streamling the parsing of argument using https://github.com/commontk/ctk-cli doing something like this:

from ctk_cli import CLIArgumentParser

def main(args):
  [...]

if __name__ == "__main__":
   main(CLIArgumentParser().parse_args())

similar approach used in https://github.com/DigitalSlideArchive/HistomicsTK/blob/06aba476ea83da672b9ab59cc9b6caa43524cb04/histomicstk/cli/NucleiDetection/NucleiDetection.py

Have you removed extension meta-information intentionally?

Yes, I removed it for now. I might change it later

Rebased against master (as of Dec 21 2021) to include c++ sources of CLI originally contributed in e9602ca but not yet available in the SurfaceToolbox:

AlignMesh
AlignMeshICP
applyVec
avgMesh
closestPoint
extractVertices
GetCurvatures
GetDirectionFeatures
ImportFromFile
InvVect
KWMToPolyData
lookupPointData
