Move buttons into an action cell
WIP assign IDs to each person

    I think we want to default id to a UUID instead of forcing the user
    to provide it.
Set data-oryx-id on each row in UI/DataTable
Dumb Collection.getById
DataTable.index_for_node(JQuery) : number
DataTable.record_for_node(JQuery) : Resource
Collection.remove
DataTable listens for Collection:remove
