/**
* Wraps a constructor function inside a curried function that can be called
* with the same arguments and returns the same type.
*
* @func
* @memberOf R
* @since v0.1.0
* @category Function
* @sig (* -> {*}) -> (* -> {*})
* @param {Function} fn The constructor function to wrap.
* @return {Function} A wrapped, curried constructor function.
* @see R.invoker
* @example
*
* // Constructor function
* function Animal(kind) {
* this.kind = kind;
* };
* Animal.prototype.sighting = function() {
* return "It's a " + this.kind + "!";
* }
*
* const AnimalConstructor = R.construct(Animal)
*
* // Notice we no longer need the 'new' keyword:
* AnimalConstructor('Pig'); //=> {"kind": "Pig", "sighting": function (){...}};
*
* const animalTypes = ["Lion", "Tiger", "Bear"];
* const animalSighting = R.invoker(0, 'sighting');
* const sightNewAnimal = R.compose(animalSighting, AnimalConstructor);
* R.map(sightNewAnimal, animalTypes); //=> ["It's a Lion!", "It's a Tiger!", "It's a Bear!"]
