#' Automatic Plot of Multi Dist Data
#'
#' @family Autoplot
#'
#' @author Steven P. Sanderson II, MPH
#'
#' @details This function will spit out one of the following plots:
#' -  `density`
#' -  `quantile`
#' -  `probability`
#' -  `qq`
#'
#' @description This is an auto plotting function that will take in a `tidy_`
#' distribution function and a few arguments, one being the plot type, which is
#' a quoted string of one of the following:
#' -  `density`
#' -  `quantile`
#' -  `probablity`
#' -  `qq`
#'
#' If the number of simulations exceeds 9 then the legend will not print. The plot
#' subtitle is put together by the attributes of the table passed to the function.
#'
#' @param .data The data passed in from a the function `tidy_multi_dist()`
#' @param .plot_type This is a quoted string like 'density'
#' @param .line_size The size param ggplot
#' @param .geom_point A Boolean value of TREU/FALSE, FALSE is the default. TRUE
#' will return a plot with `ggplot2::ggeom_point()`
#' @param .point_size The point size param for ggplot
#' @param .geom_rug A Boolean value of TRUE/FALSE, FALSE is the default. TRUE
#' will return the use of `ggplot2::geom_rug()`
#' @param .geom_smooth A Boolean value of TRUE/FALSE, FALSE is the default. TRUE
#' will return the use of `ggplot2::geom_smooth()` The `aes` parameter of group is
#' set to FALSE. This ensures a single smoothing band returned with SE also set to
#' FALSE. Color is set to 'black' and `linetype` is 'dashed'.
#' @param .geom_jitter A Boolean value of TRUE/FALSE, FALSE is the default. TRUE
#' will return the use of `ggplot2::geom_jitter()`
#' @param .interactive A Boolean value of TRUE/FALSE, FALSE is the default. TRUE
#' will return an interactive `plotly` plot.
