First implementation of new printing plan
First implementation of new printing plan

- Sheep are defined as a pprint dispatch on type 'sheep

- Turning off *PRINT-PRETTY* lets you see low-level structure
   (Good for devs bad for users?)

- Need to extend the tests to somehow check whether warnings are
  generated correctly.

- Need to add a call to #'print-sheep somewhere, or at least figure
  out where that call will go.
