Wave function collapse

Wave function collapse is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.

Write the solution for Wave Function Collapse based on the Coding Challenge 171: Wave Function Collapse and create new map 8x8 tiles with fourth T-blocks with variously directions (┤ ┴ ┬ ├) or blank tiles (space).
