This PR

  1. Adds scalar_1D_t operators to support 4th-order Runge-Kutta (RK4) time advancement for the Burgers equation solver,
  2. Defaults the Burgers solver to 4th-order accuracy in space and time (RK4),
  3. Saves the solver output to example/scripts/burgers-order-4.dat, and
  4. Adds example/scripts/animate-burgers.gnuplot, a gnuplot script that creates an animated GIF of the analytical & numerical solutions.
