[src] Update RodSection, WireRestShape and All BeamInterpolation to correctly redirect the getters to the Data

[epernod]

Add getter for:

• getBeamSection
• getInterpolationParameters
• getMechanicalParameters

Depending on the modeling:

• If BeamInterpolation is used. The method are overidden from BaseBeamInterpolation to use internal Data from BeamInterpolation.
• If WireBeamInterpolation is used: The overidden methods return the values from the WireRestShape which redirect to the corresponding method inside the BaseRodSection (depending on the current curvilinar abscissa)

Breaking:

• Remove the method GetYoungModulus by getMechanicalParameters as Poisson Ratio and Density of mass is also return at the same time.
• Rename several methods from xxxxParam to xxxxParameters and to xxxxParametersAtX (when depending on the curvilinear abscissa)
• Remove pointer to the WireRestShape in the FEM, now only use the pointer to the BaseInterpolation component which hide the use of the WireRestShape if it is as WireBeamInterpolation.

Todo: remove the MassDensity Data from the FEM. It should be defined either in RodSection or in BeamInterpolation.
