About option
when axis is horizontal, head, center, tail means top, centerY, bottom, otherwise means left, centerX, right
if view1~view5 aligh top to contentView,
options should be
let options: LineLayoutOption = [
.alignHead(to: contentView)
]
other option
let options: LineLayoutOption = [
.heightEqual(to: 30),
.widthEqual(to: otherView)
]
