ABOUT
This contains re-usable methods across several modules:
o Slick
o Slick Views
o Slick Media
o Mason
o GridStack
o ... counting.

Those modules do not all necessarily use the Blazy JS library, however
this module is a reasonable place to reduce duplication efforts and DRY stuffs.

A few things that bring those module here:
o All makes use of various lazyload goodness: IMG, IFRAME, and DIV/BODY, etc.,
  which is not currently available at D8, nor D7 AFAIK.
o All has things in common, that is, working towards performant image and media.

Please ignore the namespace. The point is to not repeat.
