Materials colors dev

Optional definition of display colours for geometric entities according to the name of their group of belonging.

To try it, run Magix3D as following :

Magix3D --groupsColors rgb.xml

where rgb.xml contains :

<Section name="ROUGE" type="container">
  <element name="color" type="color">
    <red>1.</red>
    <green>0.</green>
    <blue>0.</blue>
  </element>
</Section>

<Section name="VERT" type="container">
  <element name="color" type="color">
    <red>0.</red>
    <green>1.</green>
    <blue>0.</blue>
  </element>
</Section>

<Section name="BLEU" type="container">
  <element name="color" type="color">
    <red>0.</red>
    <green>0.</green>
    <blue>1.</blue>
  </element>
</Section>

Here are a few Python commands to execute in the console to illustrate the point :

cmd = gm.newBox (Mgx3D.Point (0, 0, 0), Mgx3D.Point (1, 1, 1), "ROUGE")
gm.addToGroup (cmd.getSurfaces ( ), 2, "ROUGE")
gm.addToGroup (cmd.getCurves ( ), 1, "ROUGE")
gm.addToGroup (cmd.getVertices ( ), 0, "ROUGE")
cmd = gm.newBox (Mgx3D.Point (1, 0, 0), Mgx3D.Point (2, 1, 1), "VERT")
gm.addToGroup (cmd.getSurfaces ( ), 2, "VERT")
gm.addToGroup (cmd.getCurves ( ), 1, "VERT")
gm.addToGroup (cmd.getVertices ( ), 0, "VERT")
cmd = gm.newBox (Mgx3D.Point (2, 0, 0), Mgx3D.Point (3, 1, 1), "BLEU")
gm.addToGroup (cmd.getSurfaces ( ), 2, "BLEU")
gm.addToGroup (cmd.getCurves ( ), 1, "BLEU")
gm.addToGroup (cmd.getVertices ( ), 0, "BLEU")

• I rebased on the main branch and skipped the commit b86be47
  that seemed to be related to #172

Works great, the rgb.xml file for testing should be completed with

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<GroupProperties XMLLoader_version="0.3.0">
  <Section name="Groups" type="container">

    <Section name="ROUGE" type="container">
      <element name="color" type="color">
        <red>1.</red>
        <green>0.</green>
        <blue>0.</blue>
      </element>
    </Section>

    <Section name="VERT" type="container">
      <element name="color" type="color">
        <red>0.</red>
        <green>1.</green>
        <blue>0.</blue>
      </element>
    </Section>

    <Section name="BLEU" type="container">
      <element name="color" type="color">
        <red>0.</red>
        <green>0.</green>
        <blue>1.</blue>
      </element>
    </Section>
