The peak intensity GUI element is now enclosed within a StaticBox.

The left hand box of the analysis frames/windows now stretches vertically.

The NOE and Rx frames are now using the base method add_execute_relax().

Fixed the layout of the execute relax button GUI element.

Removed the SetName() call (it was for debugging).

The method is now passed into add_execute_relax() to allow derived classes to specify this.

Shifted the model-free add_execute_relax() method into the base class.
