Updating a Notebook Category

Using the integer ID given, it will update an already existing category.

Please note:

The 'parent-id' field is optional here. If you pass in a parent id for a category, you will be creating a sub category. If you don't include this parameter, you will be not be creating a sub category.

** Be careful here - if you pass in the category id you are currently updating as a parent id you will remove this category from view. As you are making it a parent of itself.
