Regex Xword

Inspired by the MIT 2013 Mystery Hunt, this is the geek version of Sudoku-meet-crossword. Each clue on the grid represents a regular expression. The row of cells it points to must match this expression exactly. You can do the original Mystery Hunt version or one of the programmatically generated ones.

This is my first attempt at constructing the puzzle programmatically so, don’t judge too harshly. If there is any interest I’ll look to improve the algorithm in the next release.
