check equalities for shells and volume model

[masfaraud]

in some case it seem that equalities does not work well (pointer_memos) on Closed shell or volume modes
-> Check if eq is properly configured (non serializable_attributes...)
problematic case: shell is a colection of triangles (coming from a stl file)

Here is an example of what append using pointers_analysis

I think that a Face3D that inherits from closedShell3D with color doesn't recognize itself :
face.to_dict() #face from a closedShell3D with color
Out[43]:

face._check_platform()
data diff: ([], [], ['#/alpha'])

No problem with a closedShell3D without color

I can't reproduce the problem with a Shell with color

@masfaraud is this still a problem?
