Feature/column module

This is the column part of this module https://www.pivotaltracker.com/n/projects/911872/stories/77974996

To start with we have a generic column module that lets you pin the collection length to a max-bars attribute.

After that we'll create a applications module that lets you set a target so we can begin making calculations based on that.
No it should only run if the maxBars is less than the collections length.
