Rename early and often.

File format is recognised via simple file extension check.

Any "List" objects found will be expanded into their constituent
items, so single-element formats like json and jsonnet can use a
v1.List to capture multiple resource objects.

Repo was (at least initially) published under bitnami/ - make imports
consistent with that path.

Basic skeleton.  Can evaluate jsonnet and show the output as yaml or
json .. and that's about it.
