SYNOPSIS

use Games::Nonogram::Loader::File;
my ($h, $w, @lines) = Games::Nonogram::Loader::File->load( $file );

DESCRIPTION

This is used internally to load puzzle data from a file.

loader ignores lines which start with #
loader reads row clues first: a set of row clues per a line, and the row clues should be comma-separated.
loader regards the first blank line as the end of the row clues.
loader reads column clues, then, in the same manner.
loader regards end-of-file or the second blank line as the end of the column clues.

_XXX_
__X__
