surfaceTypeText.text should be a display name, not camelCase?

from code review #30
In the RealMoleculesViewer, I am unsure about how to review, it is possible that much of this will change. No matter I'm pretty sure we don't want the surfaceType variable value to be the display name on the viewer.

    setSurfaceType: function( surfaceType ) {
      this.surfaceTypeText.text = ( 'surface: ' + surfaceType );
    }

I'm sorry! I now see that this display is part of the 'debugText' node. Closing!
