Adapter Pattern Rollup

I think this repo could be interesting place to store various implementations of each design pattern discussed during each meeting. (They're are probably good examples online of this happening - but - who said we wouldn't learn anything by doing it ourselves?)

By crowd sourcing each pattern we could potentially have many specified languages...

TODO: (but not necessarily in this branch)

- [ ] Update design pattern root readme with some guidelines
  - Design implementation should ideally fit in a single source file? (may need to consider a folder of files?)
  - They should all follow the same pattern/design (if we're solving problem A - then each language solves problem A - only difference ends up being primarily syntax).
  - others?
