+##Subcategory Names##
+Each subcategory's name is a `/` seperated list of it parents and itself.
+This is neccesary to keep each subcategory unique. It means you can have 
+`Category 1/Foo` and `Category 2/Foo` and the won't intefere with each other. 
+Each subcategory has an attribute `shortname` which is just the name without 
+it's parents associated. For example if you had
+    
+    Category/Sub Category1/Sub Category2
+
+the name for Sub Category 2 would be `Category/Sub Category1/Sub Category2` and
+the shortname would be `Sub Category2`
+
+If you need to use the slug, it is generated from the short name, not the full
+name.
