Create a plot of the normal distribution with an area shaded in. Useful for teaching z-scores and stuff like that.

	library("ggplot2")

	#' Draw Normal Distribution Density with an area shaded in.
	#'
	#' @param lb Lower bound of the shaded area. Use \code{-Inf} for a left tail.
	#' @param ub Upper bound of the shaded area. Use \code{Inf} for a right tail.
	#' @param mean Mean of the normal distribution
	#' @param sd Standard deviation of the normal distribution
	#' @param limits Lower and upper bounds on the x-axis of the area displayed.
	#' @return ggplot object.
