o Comparison operators return bool rather than int (Note this can be a breaking
change; you may need to wrap comparisons in int() if you are using the result
in a numerical computation.)
o Foreground and background color style attributes for cells.
o Foreground, background, and hashing color style attributes for cells.
o Variable row height for cells.
o Addition of an if() conditional operator.
o Addition of a find() macro to search for a cell satisfying a condition.
