This PR is related to issue #874. It adds final and minor changes to the plots.

I have made the following changes:

  1. Removed few small bugs from Manifold.
  2. Removed tick labels from the main plot.
  3. Adjust the size of subplots in PCA.

This was issuing a deprecation warning that upper case single letter colors are no longer allowed.

@naresh-bachwani thank you so much for making these final tweaks to the projection classes; you've definitely enhanced the style and interpretability of these plots with just a few simple changes. I'll take care of fixing the tests this morning and we'll get it merged in.
