//======================================================================
//* This class provides a simple graphical interface that will display
//* the time-series information of number of macrophages and bacteria
//* across time at each integer time step.
//*
//* The constructor expects the maximum time and maximum number of agents
//* as arguments.
//*
//* The updateCounts() method will be called from within the simulation
//* code each time the simulation time crosses an integer boundary.
