)

Summary

Converts a convenient coordinate notation into puzzle-grid indices.

Parameters

this string	str	A string such as "A1-4,B-E1,E2". The letters are assumed to be columns (starting from A) while the digits are rows (starting from 1). Ranges can be combined to create rectangles; thus, A-C1-3 generates a 3×3 square.
