Material data model
In addition to classical "string" attributes like a name, and a family, 3 different specific kinds of information need to be managed to describe a material in FreeCAD. All of these kind of information do not need necessarily to be defined for the material to exist. Finally, below is the list of attributes retained to describe a material in FreeCAD.
 * properties: generic structure to store data describing the engineering properties of the material
 * chemical composition: chemical composition of the material
 * appearance: information describing how the material will look like in FreeCAD (color, shininess...)
