Layers.  Onions have layers, Ogres have layers.  I mean tags.  Tags have
layers.  The author puts their definitive tags into the META.yml and J Random
User site can layer whatever extra tags on top they want.  If the author likes
the new tags they can incorporate them into the META.yml.

The nice part about putting them into the META.yml is it follows the module
around and is available to all, not specific to just one site.
