#' Direction of Ternary Rotation
#' 
#' \code{theme_clockwise, theme_anticlockwise} (or their aliasses) are function that instructs the axes 
#' precession to be clockwise or anticlockwise respectively.
#' 
#' If the \code{tern.axis.arrow.show} value is \code{FALSE}, these functions will set it to \code{TRUE}.
