Brain DSL (draft)

[Cypher121]

Very raw version of Brain DSL. Has some samples in the sample package.

Nowhere near merge ready and has little docs, mostly putting this here to get some more eyes on it right now.

Key questions:

• Could memories be inferred from other components like activities, the way output memories can be copied from sensors? Perhaps by using memory delegates?
• There seems to be an issue with Brain.createProfile generics. Type checker not being too helpful.
• Activity tasks are indexed, but the nature of the index is not too clear. Perhaps adding a way to group like current priority(int) but without explicit number usage would be better?
