environment class ================= Every instance of the environment class is functionally a rectangular spatial domain in either two or three dimensions. The lower left corner is located at the Euclidean origin. Boundary conditions are specified with respect to the agents on each side of the domain. A fluid velocity field can be specified on a regular mesh of grid points which always includes the domain boundaries. The fluid velocity may vary in time, but the spatial mesh on which it is specified must remain constant. Analytical fluid velocity fields are also available.
