 * Class MemoryManagerMalloc: default implementation of MemoryManager
 * using malloc().
 * 
 * Typical use of this class is to create 
 * MemoryManager* mm = new MemoryManager(sizeof(YourClass)); 
 * where YourClass has operators new and delete redefined:
 * void* YourClass::operator new(size_t, MemoryManager* mm)
 * { return mm->newData(); }
 * void YourClass::delete(void*) { } // do not deallocate memory here
 * Then, create objects with obj = new(mm) YourClass(), and destroy them with
 * delete obj; mm->deleteData(obj);
