Will allow xarg behavior to fetch resources across multiple types.
Changes 'create', 'get', 'update', 'stop', and 'delete' to output
<resourceType>/<name>.
Create a unified Builder object for working with files, selectors,
types, and items that makes it easier to get multi-object functionality.
Supports all of the behaviors previously in resource.go, but with
additional flexibility to allow multi-type retrieval and access, directories,
URLs, nested objects, and lists.
