Todd	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.	2017-09-16 16:52:14 -05:00
Todd	fb43078e87	formula: add support for referencing other sheets ... This adds support references like 'Sheet 1'! so that formulas can pull values from other sheets.	2017-09-16 10:33:13 -05:00
