# Ram's original Wes Anderson code: https://github.com/karthik/wesanderson/blob/master/R/colors.R

#' A Wes Anderson palette generator
#'
#' These are a handful of color palettes from Wes Anderson movies. 
#' @param n Number of colors desired. Unfortunately most palettes now only have 4 or 5 colors. But hopefully we'll add more palettes soon. All color schemes are derived from the most excellent Tumblr blog: \href{http://wesandersonpalettes.tumblr.com/}{Wes Anderson Palettes}
#' @param  name Name of desired palette. Choices are: \code{GrandBudapest}, \code{Moonrise1},  \code{Royal1},  \code{Moonrise2}, \code{Cavalcanti},  \code{Royal2}, \code{GrandBudapest2},  \code{Moonrise3},  \code{Chevalier}, \code{BottleRocket}, \code{darjeeling}, \code{darjeeling2} 
#' @param type Set to continuous if you require a gradient of colors similar to how heat map works.
#' @export
