#' Generator function for skinny hypercubes
#' 
#' This function generates a \eqn{d}-dimensional skinny hypercube \eqn{[-1,1]^{d-1}\times [-100,100]}.
#' 
#' @param dimension The dimension of the skinny hypercube.
#' 
#' @return A polytope class representing the \eqn{d}-dimensional skinny hypercube in H-representation.
#'
#' @examples
#' # generate a 10-dimensional skinny hypercube.
#' P = gen_skinny_cube(10)
#' @export
