Richer CellReference commands

[jkomoros]

• [x] [startRow, startCol, endRow, endCol] to select a rectangular region
• [x] [] to select all cells
• [x] a 2-index cellReference should literally just expand into [foo, bar, foo, bar]
• [ ] Allow setting a rectangle of values for a rectangular region
• [ ] Allow a list of cells and rectangles for a single value statement, e.g. [true, [[3,4], [5,6], [7,8,10,8]]
• [ ] Allow some kind of filtering statement to select only cells in a region that match some critera
• [x] Not totally restricted to this issue, but allow a reset command that resets all affected cells to their default values
• [x] Test invalid indexes throw

Once you can do multiple references, the signature should change to:

{
  "cells": [
    ["value", 1.0, [
      [3,4],
      [],
      [1, 2, 4, 4]
    ]]
  ]
}

... Or is that more confusing?
