This function allows to set the initial conditions for our problem to be solved, by default particle locations are randomly set. Remember particle properties must also be defined here.
A virtual function with no implementation but can be overriden.
This sets up the particles initial conditions it is as you expect the user to override this. By default the particles are randomly distributed
