[pyooml] Automatic generation of part properties for simplifiying the user API

[Obijuan]

Currently many of the pyooml clases (cube, cylinder...) are duplicating the properties. All the properties created with addProperty belongs to the freecad objects (.obj). They should be replicated in the pyooml classes for accessing easily.

Ej.

c.lx (map property) --> c.obj.lx (real property)

How can it be automatically mapped from c.obj to c? This way, it would be easier for the user to created derivate classed.
