kindergarten-garden: add canonical data (#770)

Closes #565

Notes:

* The default students indicated in the README are assumed, and 
  alternate students are indicated as input when appropriate.
* While some tracks tested all 12 students for the full garden, it only
  seemed necessary to include a few tests here.
