TOWER_SIDESconstant

Towers (Skyscrapers) as a string: the cells, then the clues around the edge.

The cells come first, row-major, as every number grid is written (. for empty; most puzzles print none). Then one character for every place a clue can stand outside the square, four sides of size: along the top left to right, along the bottom left to right, down the left top to bottom, down the right top to bottom. A digit is how many towers can be seen from there; . is no clue. A 7×7 is 49 + 28 characters.
