Running Exw.exe spring.ex..
-------------------------------------
Note: There are other simulation scenarios available by changing the source code comments

{ time, spring potential, equilibrium length, velocity_1, position_1, velocity_2, position_2 }


the second mass is displaced slightly inwards, the spring moves with oscilation and settles into a new equilibrium
