Path_RoundedComposite::Clone() doesn't copy F_base_start and F_base_via

[DobbyPeng]

I'm trying to use Path_RoundedComposite::Clone() to clone a Path_RoundedComposite object.
But I found that Path_RoundedComposite::Clone() doesn't clone F_base_start and F_base_via.
If I call Path_RoundedComposite::Finish() on the clone, it doesn't know the last pose.

orocos_kinematics_dynamics/orocos_kdl/src/path_roundedcomposite.cpp

Lines 198 to 200 in b35de34

	Path* Path_RoundedComposite::Clone() {
	return new Path_RoundedComposite(static_cast<Path_Composite*>(comp->Clone()),radius,eqradius,orient->Clone(), true, nrofpoints);
	}

According to the constructor:

orocos_kinematics_dynamics/orocos_kdl/src/path_roundedcomposite.cpp

Lines 55 to 59 in b35de34

	Path_RoundedComposite::Path_RoundedComposite(Path_Composite* _comp,
	double _radius, double _eqradius, RotationalInterpolation* _orient,
	bool _aggregate,int _nrofpoints):
	comp(_comp), radius(_radius), eqradius(_eqradius), orient(_orient), nrofpoints(_nrofpoints), aggregate(_aggregate) {
	}

Everything is taken into account correctly. So the problem is somewhere else.

The variables F_base_start and F_base_via are marked as cache in the header. But I am not really sure that is correct.

But this code is really old and I don't have a clue about what is and should be doing. So please make your case why things need to change in a PR.

In my case, I want to create a composite path of serval target poses. And in progress, I want to check if poses in the path can be reached by the robot.

So, I want to clone a path and call the Finish() on the clone. Then get every 1 mm(just for example) of pose for inspection.
