title: Blender Python API add property to object
body: <p>Here's what I'm trying to do:</p>
  
  <pre><code>reference_object= bpy.context.active_object
  reference_object.add_variable(name='some_property',value=5)
  reference_object.some_property
  </code></pre>
  
  <p>and it would print back 5</p>
  
  <p>I basically am trying to add a property to an object that's already been created and does not have the particular variable I'm trying to add in it's class. I tried looking up how to do this but I cannot seem to understand some of the other posts. Any advice would be great.</p>
