In dan410/sfdasim: Simulates spatially dependent functional curves and data

#' Plots the observed data from a functional data set
#' 
#' For observed functional data (arranged in a data frame with a column named
#' ID which contains integer values indexing the curves and a column named Time containing
#' values on the x-axis and a column named X for the observed response) this function will
#' produce a plot of the observed data. By default the points for each curve are connected by lines.
#' 
#' @param dat Data frame containing observed functional data. Must have columns "ID", "Time", and "X" (see details)
#' @export
