Styling audits

Fixing lots of tiny things, next step is a responsive audit.
I was curious what those col-lg- prefixes are.  

I think they're for a different with, but what are they exactly.  

The reason I ask, is because I want to have these mixins to have a clear path to be their own library, so I"m wondering if it's better to put them into the formOptions.fieldLabelClasses or straight up into the template.

If you put them into formOptions, they will be specific only to our application, otherwise they will go into what will eventually be a library.  

I've also thought about possibly ripping out all default sm's from the jade and putting them into an it's own separate object -- but that's definitely not in scope right now.

Wanted to know your thoughts @ainsleywagon  | @chrisrodz.  Don't see this as a blocker for merge though
