Storing labels

[giladgray]

Do they need to be stored? Or can they just be ignored? We just "assume" undefined components are labels. I guess if you later try to give a label a value then that would be a problem.

I stored labels simply as a way to provide feedback to the dev. I figured that if I printed a message, it would help with any typos; it's pretty easy to break things by having a slight typo in the component name, which then causes systems to not be invoked without anything clearly wrong.

I hadn't considered the case of a label being upgraded to a full defined component though.
