#' ggtern themes
#'
#' Themes set the general aspect of the plot such as the colour of the
#' background, gridlines, the size and colour of fonts.
#'
#' @param base_size base font size
#' @param base_family base font family
#'
#' @details \describe{
#'
#' \item{\code{theme_gray}}{
#' The signature ggplot2 theme with a grey background and white gridlines,
#' designed to put the data forward yet make comparisons easy.
#' }
#'
#' \item{\code{theme_bw}}{
#' The classic dark-on-light ggplot2 theme. May work better for presentations
#' displayed with a projector.
#' }
#'
#' \item{\code{theme_linedraw}}{
#' A theme with only black lines of various widths on white backgrounds,
#' reminiscent of a line drawings. Serves a purpose similar to \code{theme_bw}.
#' Note that this theme has some very thin lines (<< 1 pt) which some journals
#' may refuse.}
#'
#' \item{\code{theme_light}}{
#' A theme similar to \code{theme_linedraw} but with light grey lines and axes,
#' to direct more attention towards the data.
#' }
#'
#' \item{\code{theme_dark}}{
#' The dark cousin of \code{theme_light}, with similar line sizes but a dark background. 
#' Useful to make thin coloured lines pop out.
#' }
#'
#' \item{\code{theme_darker}}{
#' A darker cousing to \code{theme_dark}, with a dark panel background.
#' }
#'
#' \item{\code{theme_minimal}}{
#' A minimalistic theme with no background annotations.
#' }
#'
#' \item{\code{theme_classic}}{
#' A classic-looking theme, with x and y axis lines and no gridlines.
#' }
#' 
#' \item{\code{theme_rgbw}}{
#'  A theme with white background, red, green and blue axes and gridlines
#' }
#' 
#' \item{\code{theme_rgbg}}{
#' A theme with grey background, red, green and blue axes and gridlines
#' }
#'
#' \item{\code{theme_void}}{ 
#' A completely empty theme.
#' }
#' 
#' \item{\code{theme_custom}}{
#' Theme with custom basic colours
#' }
#' 
#' \item{\code{theme_matrix}}{
#' Theme with very dark background and bright green features
#' }
#' 
#' \item{\code{theme_tropical}}{
#' Theme with tropical colours
#' }
#' 
#' \item{\code{theme_bluelight}}{

#' }
#' 
#' \item{\code{theme_bluedark}}{
