  Write a function named: lazyAdder(firstNum). The lazyAdder function will
  accept a number and return a function. When the function returned by lazyAdder
  is invoked it will again accept a number, (secondNum), and then return a function.
  When the last mentioned function is invoked with a number, (thirdNum), it will
  FINALLY return a number. See below for examples!
  
  Example 1:
  let firstAdd = lazyAdder(1);
  let secondAdd = firstAdd(2);
  let sum = secondAdd(3);
  console.log(sum); // prints 6
  
  Example 2:
  let func1 = lazyAdder(10);
  let func2 = func1(20);
  let total = func2(3);
  console.log(total); // prints 33
