Tippe top: Elasticity

The employed model has another feature.
We consider the elastic properties of the top and the surface. This results in a contact area, which means that our tippe top falls down in finit time and doesn't rotate forevermore.
The elasticity is also crucial in another way: Many trials and preceding investigations have shown, that the top occasional take off the surface (which can be observed acoustically by rattling). So a model without elasticity and the assumption of permanent ground contact turn out to be unrealistic.
