// You will be given the calendars of our businessperson and a duration for the

// Description:
// 
// One of the services provided by an operating system is memory management. 
// The OS typically provides an API for allocating and releasing memory in a 
// process's address space. A process should only read and write memory at
// addresses which have been allocated by the operating system. In this kata you
// will implement a simulation of a simple memory manager.
// 
// JavaScript has no low level memory API, so for our simulation we will simply
// use an array as the process address space. The memory manager constructor

// * Given some data that looks like this:
// 
// let data = [
//   {
//     key: 'a',
//     value: 'a1',
//     children: [
//       {
//         key: 'b',
