Full Icon View pages should contain a usage example section

[mririgoyen]

As a user of the Pictogrammers website, I'd like to see examples of how I might implement an icon I am considering using. This would show the icon in various situations... in a button, in a dashboard, on a poster, in a toolbar.

AC:

• Add a new section to the Icon View while in full-screen mode (hide in modal view) that contains usage examples.
• Be certain all examples handle responsive viewports.
