988f2e3290 spreadsheet: move ColumnToIndex/IndexToColumn
Create a spreadsheet/reference package and put these functions
there. This prevents both duplication across the formula &
spreadsheet packages and a cyclic reference.

00be1d037c formula: support evaluating array formulas
Array formulas are entered in Excel by pressing
Ctrl+Shift+Enter to finish the formula.  The resulting
formula is entirely in one cell, but its computed results
expand into cells the size of the array result.

23e428e770 formula: return array instead of list for ranges
This will be required for functions that need to know
the structure of the input.

5a5c16b89a formula: add initial support for cell arrays
This is a pretty uncommon feature from what I can tell
and is not fully supported. The example for the MDETERM
function uses an array though, so this will at least add
enough support for the examples to compute correctly.

We can take advantage of cached formula results that Excel/LibreOffice
insert to ensure that our formula results match the expected results.
