Relative Coordinates

This is a coordinate system adapted from Go that allows us to talk about important moves in the same way, regardless of board size. We use YX instead of XY because row is more important in Hex, and because we're taking the bottom red edge as our perspective, as is customary. This also most closely resembles how people talk about certain moves already. 4-4 becomes 44. 5-4 becomes 54'.

• A: 44
• B: 54'
• C: 5'4
• D: 4'4'
• 1: 2'3
• 2: 5'2

I left 3 out because it requires some more explaining. On it's own, 3 would be 62. However, in the context of stones 1 and 2, it is better to label it as 8'2. This is because the sequence 2'3, 5'2, 8'2 is a common opening sequence, and labeling it as 8'2 means it won't change with board size. The row that 3 is on is based off of the 5'2 stone, not the red edge.

Edges

We now have a much nicer way to refer to the edges: red, red', blue, blue'.
