Color support in MeshComponent SpecificRepresentation

As a	CamiTK and CEP developer
I would like to	display colored meshes from cell/points data
So that	This will allow displaying meshes with color specified as RGB/RGBA values for each cell or point (e.g. electrode model)
Epic/Topics	MeshComponent color

Description / Overview

In MeshComponent, SpecificRepresentation does not support using 3D or 4D data as RGB/RGBA color encoding for cells or points. Models of objects such as robots or implanted medical devices could be loaded and displayed using colors defined in the Mesh itself.

Hints

A @TODO comment in MeshComponent.h for the SpecificRepresentation enum shows that this part of the code is relevant for this feature.

Acceptance tests

• Open a MeshComponent which uses color support → Mesh should be displayed with the specified colors
• Add a tutorial showing RGB color data used to color a mesh: not needed, there is already a test file check-with-color-pointdata.vtk that needs this function.
