[ic] Components - Random - Foundation

[interchange-users@icdevgroup.org (ArmyNavy.com Webmaster)]

Hi All

I noticed in the tarball of 4.8.5 that there is a single random component 
in Foundation - random. 

However, when you build a catalog based on Foundation, you get 3 
random components - random, random_vertical, random_horizontal.

Where did the _vertical and _horizontal come from?

I'm trying to customize some components (and in general understand 
how components work). 

Thanks very much.
