Course and Section controller + foundation

Added Foundation Framework
Ability to Add Courses and Sections related to them. 
I've also checked the Database and every time a Course and Section is created, they are actually in the database with the correct relationships
Seeded some categories
-- Don't know how to seed courses and sections (since they have to be related to a signed in user_

Possible next steps:
Course show page (with links to the section page)
nav bar (with +, Course, Search and User tabs) as a partial to be added at the top of all pages  (or in layout)
Ability to add Section (non parse pretty version).
Edit Course Name and description (within Course show page)
Edit Section (on Sections index)
