[WIP] Development version (PIAF)

[pradal]

No description provided.

[pradal]

Please, name your modules (python.py files) with only lower cases.
And also functions.

Use ratp2vtk rather than RATP2VTK
And do not use pyratp into module names.
Because the modules are part of the openalea.ratp package

[pradal]

@cyrilbz : Do you need to rename the package openalea.ratp into openalea.pyratp?

[cyrilbz]

@pradal No, no need to rename the package I think!
I updated my branch with the new 3D voxel viewer (based on PyVista library), see attached screenshot.

I will start now satisfying your request about upper/lower cases, and will let you know when I am done.

@pradal I resolved the upper case issue for module names. Changing the file name RATP2VTK.py into lower case requires changing meson.build in src/openalea/ratp, and it's not the only file name that contains upper cases... let me know if you want me to update all of them!
