title: Detecting intersecting SCNGeometries and returning it as an array
body: <p>I am trying to find a way to detect whether or not an <code>SCNGeometry</code> is intersecting with any other <code>SCNGeometries</code>. I can't seem to find anything in apple docs to support this notion, nor anything online either.</p>
  
  <p>As of right now, the only method I can think of doing is enabling the Physics Engine and doing contact tests, but I want to try and avoid it if possible.</p>
  
  <p>Basically, all I want to do is throw an <code>SCNGeometry</code> onto the a scene, and detect what <code>SCNGeometry</code> it is touching (Basically getting an array of geometries) so that I may process further steps.</p>
  
  <p>There is no code as of yet,  I am trying to research how if possible it can be done.</p>
  
  <p>I can also accept code in any programming language, so feel free to provide an answer in what you feel most comfortable with.</p>
