/** Spreadsheet-style string representation of points.
Can be used as a template argument for Point.
Columns are represented as letters including the letter 'J'. After 'Z',
multi-letter combinations are used: 'AA', 'AB', etc. Rows are represented
by numbers starting with '1'. Note that unlike in spreadsheets, row number
1 is at the bottom and increases to the top to be compatible with the
convention used in chess. */
