Single-slit and double-slit diffraction via Schrodinger's equation in 2-D

Visualizing single-slit and double-slits diffraction via solving Schrodinger's equation in 2d. The mathematical derivation of the FFT2-compatible form of Schrodinger's equation is also included.

reminder: make sure you have ffmpeg installed in the environment you are working with.
