Hi guys,

just pulled some helper functions for cylinders and some related examples.

I also created a script examples/cylinders/cylinderconnection-roots.py which 
is aimed to replace examples/chained-cylinders/chained-cylinder-roots.py. I 
couldn't get the box-gridConnection interactions to working, but I guess I am 
missing something.

In addition, have a look at examples/cylinders/cylinder-cylinder.py. Is there 
a way of linking the rotation of the GridNodes to the GridConnection/Cylinder? 
I guess increasing the bending stiffness would help but how can we make it 
independent of this? Any suggestions?

Cheers
Klaus
