    Generate coordinates for a ridge line.

    Will be a series of coordinates, starting a start_loc (length 2).
    The maximum distance between any adjacent columns will be
    `max_distance`, the max distance between adjacent rows
    will be `map_gap'.

    `max_locs` should be the size of the intended matrix. The
    ending coordinates are guaranteed to be less than `max_locs`,
    although they may not approach `max_locs` at all.
