Friction extension type
The Friction extension type represents a friction coefficient, indicating how much resistance
a material or surface provides against motion. The values range from very slippery (like ice)
to extremely grippy (like duct tape).
This extension type implements the double interface, making it usable wherever a double is expected.
It provides several predefined friction values, from the near-frictionless ice to the super sticky duct tape.
You can also create custom friction values using the Friction.custom() factory constructor.
