#' Batch apply the carousel presentation style to a list of questions belonging to various groups
#'
#' This takes two data.tables (not lists in the R sense of the word!)- a list of array subquestions that includes the qid, gid, parent_qid, and title, and a list that contains the empty questions (with "title", "gid", and "qid") that are within the arrays group which should receive the html injection- and applies the carousel javascript/html format to them
#' @param Array_Question_List A list of the subquestions that should be transformed into the carousel format
#' @param Top_Question_List A list of the "TEXT" questions that are in the group with the respective array question, and that should "receive" the html/javascript payload
#' @export
#' @examples \dontrun{
