Begin demo rework with more examples.
Fixed a bug which occurred in some rare cases where one of the sublabels would remain unaffected by text color change e.g. black, while scrolling inside of a collection view (possibly any such container).
Implement trailing and leading buffers.
Add buffers to demo.
Help formatting tweak.
Correct bug with continuous-type second label frames. Eliminated some code duplication too.
Add a changing attributed text to the demo.
Add table view basic, non-working implementation to demo.
