In obfuscatoR: Obfuscation Game Designs

#' Generate obfuscation designs
#' 
#' The function takes the list of design options \code{design_opt_input} and 
#' generates one or more obfuscation designs subject to the specified 
#' restrictions. A full specification of all the options available can be found
#' in the manual along with detailed examples of different designs. At a minimum
#' the user must supply the number of rules and actions, i.e. the dimensions of
#' the design problem. 
#' 
#' @param design_opt_input A list of user supplied design options.
#' 
#' @return 
#' A list of matrices with rules and actions
#' 
#' @examples
#' design_opt_input <- list(rules = 4,
#'                          actions = 5)
