#' Test Whether Action Is Valid
#'
#' @param player An object of the S4 class player.
#' @param action A string that represents the players action when it is their turn.
#' It is usually generated using the input_action() funciton.
#' @param turn An integer representing the index of the player who's go it is.
#' @param bets A vector containing the current value of each player's
#' contribution to the pot.
#' @param raise A numeric value representing the most recent raise made
#' by any of the players.
#' @return A list containing a logical value representing the validity of the action.
#' The list will have a second element when the logical value is FALSE, which
#' contains a string detailing the nature of the problem.
