One thing I accomplished today was to fix the lograys function. It did not work appropriately for separate paths of movement that partially overlap, as we get in Chess66. As it found spaces a piece could legally move to, it would add them to an array, and it would stop if it ever reached a space already in the array. This may be fine for Spherical Chess, in which paths do not usually overlap, but it was a problem for Chess66. So, I replaced the single array with two arrays. It uses one array to keep track of the spaces found in the current direction of movement being checked. It breaks out when it reaches a space already in the array, as this is an indication of a move looping back on itself. When it is done checking a particular direction, it merges this array into an array of all spaces the piece can reach so far, and it empties the array for the spaces that can be reached by moving in a particular direction.

I've also noticed that I was expecting more of unlink than it can actually do. I was expecting it to be able to unlink indivdual directions, but all it does is completely unlink coordinates, which is overkill. I may modify it to work as I was expecting it to.
