/**
 * Wraps a constructor function inside a curried function that can be called
 * with the same arguments and returns the same type. The arity of the function
 * returned is specified to allow using variadic constructor functions.
 *
 * @func
 * @memberOf R
 * @since v0.4.0
 * @category Function
 * @sig Number -> (* -> {*}) -> (* -> {*})
 * @param {Number} n The arity of the constructor function.
 * @param {Function} Fn The constructor function to wrap.
 * @return {Function} A wrapped, curried constructor function.
 * @example
 *
 *      // Variadic Constructor function
 *      function Salad() {
 *        this.ingredients = arguments;
 *      }
 *
 *      Salad.prototype.recipe = function() {
 *        const instructions = R.map(ingredient => 'Add a dollop of ' + ingredient, this.ingredients);
 *        return R.join('\n', instructions);
 *      };
 *
 *      const ThreeLayerSalad = R.constructN(3, Salad);
 *
 *      // Notice we no longer need the 'new' keyword, and the constructor is curried for 3 arguments.
 *      const salad = ThreeLayerSalad('Mayonnaise')('Potato Chips')('Ketchup');
 *
 *      console.log(salad.recipe());
 *      // Add a dollop of Mayonnaise
 *      // Add a dollop of Potato Chips
 *      // Add a dollop of Ketchup
