Sympy Plot Backends v1.1.1

What's Changed

• Added color_func keyword argument to:

  • plot to apply custom coloring to lines.
  • plot3d and plot3d_parametric_surface to apply custom coloring to 3D
    surfaces.
  • to accomodate color_func, ParametricSurfaceSeries.get_data() now
    returns 5 elements instead of 3.

• Added plot range to default settings.

• Implemented a custom printer for interval math to be used inside
  ImplicitSeries.

• Added plot3d_implicit to visualize implicit surfaces.

• MatplotlibBackend now uses default colorloop from plt.rcParams['axes.prop_cycle'].
