title: C++ Using sizeof() to determine size of an Octree
body: <p>Let's say <code>Octree()</code> is a container with Elements of type double.</p>
  <p>Can I use <code>sizeof(Octree)</code> to determine how much memory in bytes is taken up by my octree?</p>
  <p><code>Sizeof()</code> should change if I change the resolution/depth of my octree - which does not seem to be the case when I test it.</p>
  <p>Is there a way I could determine the dynamically allocated memory size of my octree?</p>
