Arguments

layer	A layer object that represents the celtic knot. Components will be sections of the ribbons.
lineOrder	??
angles	??
basis	data.frame containing information about the anchor points of the knot.
knotOrder	??
knotFillColour	The colour of the knot
knotBorderColour	The colour of the knot line border
clockWiseCorners	??
flipCorners	??
distance	gives the distance of line(s) from the middle of the ribbon. This controls the width of the ribbons.
knotMode	controls the style of a knot. Options are "DEFAULT", "INNERRIBBON" and "DOUBLE". Default is one ribbon, innerribbon is one ribbon inside another, double is two parallel ribbons.
...	parameters passed to the layer and the layer function object. See "details" for more information.
