// 'column'. If you set it to 'row' the bookings are read from left to right within a day, but from
// top to bottom within the interval (week/month), so you have to read the display by snaking down
// the columns, which is potentially confusing. If you set it to 'column' then the bookings are in
// order reading straight down the column, but the text within the bookings is usually clipped unless
// the booking lasts the whole day. When the days are along the top and the text is clipped you can
// at least see the first few characters which is useful, but when the days are down the side you only
