 By default, Rails 3.2 loads everything in app/javascripts and everything in app/stylesheets on 
 every page, despite controller-specific file naming. If you want to load controller-specific 
 files only on views from their respective controllers, you need to change the manifests and the 
 layout. The basic idea is to NOT require the entire trees, but only specific subfolders, in the 
 manifests, and then load the controller-specific files separately in the layout.

 Any file you DO want loaded on every page should be placed in app/assets/javascripts/general or 
 app/assets/stylesheets/general.

 For this to work in production, you also need to ensure that the individual files are precompiled by modifying your production.rb file, listing all of the controller-specific files.

 * compiled file, but it's generally better to create a new file per style scope.
