Group.align had row and column parameters swapped in many (but not all) places. I think I caught all in the docstring. Did a simple search-replace in the function code.
fix documentation for group.align -- row and column were swapped
Yes you're right, I'll merge this in, but I'm going to remove all mention of columns and rows because I think it's more confusing than helpful. Will replace with a simple width and height.
