Problem/Motivation
Sometimes you have an array of attributes and it would be nice if you could addClass, removeClass, setAttribute, etc. rather than trying to do array manipulation.
Proposed resolution
Add a function to our Twig extension to allow creating an Attribute object from an array of attributes.
Remaining tasks
All of them.
User interface changes
n/a
API changes
API addition: New Twig function added (name TBD).
Data model changes
n/a
