In matuR: Athlete Maturation and Biobanding

#' Height (current + predicted) vs growth curves plot for males.
#'
#' This function returns a ggplot object showing the **current** and **predicted height** vs normal growth charts for american population.
#'
#' Data for growth charts was obtained from the National Center for Health Statistics.
#'
#' Please visit \url{https://www.cdc.gov/growthcharts/percentile_data_files.htm} to learn more about this information.
#'
#' Be aware, players from different populations to the one used on these growth charts may not be well represented.
#'
#' For females, use documentation for **`plot_growth_female()`**
#'
#'
#' @param data A data frame. The object containing the raw data we wish to analize.
#' @param athlete A character string with the name of the athlete we wish to plot.
#' @return A plot `(ggplot)`
