* AP® Computer Science Marine Biology Simulation:
* The SimpleMBSDemo2
class provides a main method that creates
* a simulation of a number of fish swimming in a bounded environment.
* It also creates a simple window in which to view the environment
* after each timestep in the simulation. This version of the MBS demo uses
* an object of the Simulation
class.
*
*
* This class will NOT be tested on the Advanced Placement exam. * *
