Really really simple program to choose a crochet pattern for me to follow, given some basic rules about alternating colors.
- Can't crochet using two colors from the same color category next to each other
- Can't crochet using a color I've run out of
- Bias towards newness - there's a .75 chance that the next color will be in a different color category from the categories of the last three colors chosen (unless this is not possible given the available stock of colors)
