Bootstrapped grid like singly linked-list in 2D
Continued to sketch out skeletal grid module
Grid the grid from a list of lists (rows)
Introduce the concept of an inner zip
Added "top as list" as I continue to explore grid
Added "left (column) as list" while exploring grid
Another increase of difficult progress on grid
Starting to put the pending tests back in place
Bolstering with more tests before adding behavior
Reformatted now that some stuff is working
Re-enabled all but one pending test

Got hung up on some stupid stuff... man, my brain is tired. This has
been a mind-bending but productive session.
