#' Get Games
#'
#' get_current_games provides an API to return the current rounds matches in a data frame.
#'
#'
#' @param user monash username, in text
#' @param pass monash password, in text
#' @param comp comp type, should be one of "normal", "gauss" or "info"
#' @param round (optional),  round number to return. If not provided, will try find the current round.
#'
#' @return A tibble, containing the matches from the currently available tipping round
#' @export
#'
#' @examples
#' \dontrun{
#' get_games(user, pass, comp)
#' }

#' Submit Tips
