end

#crossings ⇒ Object

used to find indices where we have table ‘+’ crossings. in cases where the colspan > 1, then we will skip over some numbers if colspan is always 1, then the list should be incrementing by 1.

skip 0 entry, because it’s the left side. skip last entry, because it’s the right side. we only care about “+/T” style crossings.
