 #021-022 Method of characteristics for scalar 2-D linear equations.
          Important: CAUSALITY. Explain and justify for continuum systems
          because of the presence of small dissipative terms. Show example
          of backward heat equation.
          Example: traffic flow control at ends of a tunnel.
 #022 --> Start with nonlinear kinematic waves.

          Definition of linear, semi-linear, and quasi-linear.

 #023 Begin with quasi-linear kinematic waves. Wave front distortion
