The picross rules variant.
BASIC is the most basic set of rules, with only one color and only

sets color_lines and color_columns.

Picross puzzle representation.
For example, take the following basic black and white puzzle::
1
1 3 3 2
3 X X X
2 1 X X X
2 X X
1 X
1 X
It is represented the following way::
lines = [(3,), (2, 1), (2,), (1,), (1,)]
columns = [(1,), (3,), (1, 3), (2,)]
Note that empty lines and/or columns are either represented with an empty
tuple or as (0,) depending on what is convenient for the module,
e.g. the following pattern::
1 1 1
1 1 1
3 X X X
0
3 X X X
Is either represented the following way::
lines = [(3,), (), (3,)]
columns = [(1, 1), (1, 1), (1, 1)]
Or the following way::
lines = [(3,), (0,), (3,)]
columns = [(1, 1), (1, 1), (1, 1)]
Colored puzzles, on the other hand, associate colors to a puzzle by
populating color_lines and color_columns. Since it is possible to
distinguish groups by using the color, it does not require gaps between
groups, which can just be stuck together.
For example, take the following colored puzzle::
3G
2G 4G 2R 4G 2G
3G G G G
5G G G G G G
5G G G G G G
1G 1R 1G G R G
1R R
It is represented the following way::
lines = [(3,), (5,), (5,), (1, 1, 1), (1,)]
columns = [(2,), (4,), (3, 2), (4,), (2,)]
line_colors = [(G,), (G,), (G,), (G, R, G), (R,)]
column_colors = [(G,), (G,), (G, R), (G,), (G,)]
Where R = 0xFF0000 (i.e. 16711680) and G = 0x00FF00 (i.e. 65280), since
color components are integers representing sRGB colors.
