Merge pull request #3 from widagroup/master

GetCategoryChildren almost working - returns a view instead of JSON now
Debugged GetCategoryChildren + moved accordian code to a function to be called when the treeview is updated.
Refactored javascript so that treeview is all in one function + bug in treeview - styles not being applied correctly.
