OSC Chemistry Template WIP

The initial build of the OSC Chemistry Template as a work-in-progress pull request for review and comment.  We are about 75% complete for our first 80% template. :)  Test data has been created to reflect the look and feel of the annotated template.  
For this one, and one below... yes, I agree that I think we eventually should compress the parent .less files and purge them of these and perhaps place in slots.  For now, I just created them as we have our other books.  Once we agree where to move these, we could possibly take our four books (chemistry, economics, history, precalculus, psychology) and do this operation for all five at once
