title: Manually Open custom inspector for serializable object
body: <p>I have a window editor that holds nodes. I would like to open a custom inspector when one of these nodes is selected. The node class is a custom serializable class. Is this possible?.</p>
  
  <p>It seems that custom inspectors can be created manually through the Editor.CreateEditor method but can't see how to let it appear docked like an usual inspector in the unity inspector window.</p>
  
  <p>I would like to achieve the same behaviour that we have when we select a gameobject in sceneview that inmediately show properties for the object (Components, etc...) in the unity inspector.</p>
  
  <p>Cheers</p>
