added cardset model and database
cardsets added to database and homes/index view, no testing so far
able to add a cardset through views, css still needs work, and links from page to page need to be sorted out.
progress on adding cardset views and updating controller, not done yet. Added debugger gem
added public and private cardset partials, worked on css for left and right spacing
css for navigation bar nav-float-left style is done
divided css into separate files so that it's easier to read.
changed cardsets' routes so that there is only cardsets :index and :show
changed cardsets' routes again, added :create
continuing to update css files
satisfied with cardsets views, logic, and safety
