| WeblogCategoryAssoc represents association between weblog categories
in the weblog category hierarchy. For each category, there will be zero
or one parent category association and zero or more grandparent
associations.
Creating a new Cat
WeblogManager creates new Cat, not a PO
Cat has a parent Cat or null if parent is null. Parent must be PO.
On save, CatAssoc will be created for Cat.
Saving an existing Cat
If Cat has a new parent Cat, then update all of Cat's CatAssocs
