Function curry

lodash.js:10297–10302

* Creates a function that accepts arguments of `func` and either invokes * `func` returning its result, if at least `arity` number of arguments have * been provided, or returns a function that accepts the remaining `func` * arguments, and so on. The arity of `func` may be specified if

(func, arity, guard)

     * // => [1, 2, 3]

    function curry(func, arity, guard) {
      arity = guard ? undefined : arity;

    /**
     * This method is like `_.curry` except that arguments are applied to `func`
