Solve the picross!

http://en.wikipedia.org/wiki/Nonogram

The arguments (horz and vert) are cells containing the clues, e.g:

horz = { 2, [1, 1], [] }; vert = { 2, 1, 1 };

means

You have to return the completed picross, a logical or double matrix with a 0 for a white case and a 1 for a black case. If we solve the previous example:

So, the output argument should be:

picross = [ 1 1 0 ; 1 0 1 ; 0 0 0 ];

You have to do some guessings and optimize your code to pass the test suite.

Have fun!
