DESCRIPTION:
Simple spreadsheet, based on rebocalc.r, with formulas calculated left to right, top to bottom.
A cell is either a scalar value, string, or a formula starting with "=".
Scalar values are automatically right-justified, series values left-justified.
Remember to put spaces between each item in a formula and use () where needed.
