The test_slider.cpp-example contains a basic spring. It shows how to 
implement springs for a slider joint, but i guess the implementation for 
a hinge joint won't be much different. Maybe you want to take a look.

Just set the hinge dParamVel value to zero and dParamFMax to some 
reasonable force.
