Create a structure called "atom", and create an instance of that structure based on a real atom. Give it any physical property you think is important to an atom, and set the values to something realistic. Also give the atom x, y, and z coordinates as part of the structure. Run a simulation from Main() that calls a function to increment the location (coordinates inside the structure) of the atom in x, y, or z, or make it move in some predefined pattern.
