2. Added animation for fitting GP
3. Added plot of inducing points
4. Added animation for fitting inducing point GP
5. Added example showing impact of lengthscale#

1. Adds a simple example for binary GP classification
2. Adds a simple example for multi-class GP classification using the
   Iris dataset
3. Removes deepcopy for inducing points location, instead use
   np.array.copy()
4. Changes the animations from HTML to GIFs (each GIF is 1-2 MBs)
5. Miscelleaneous trivial cleanup and Black formatting

1. trivial example for deep kernel learning
2. combination of kernels
3. using ARD in DKL example
4. miscelleanous cleanup

1. cleaned up warning using try, excepy block
2. supressed the matplotlib stray text being printed using _ = ...()
