revisit nakamura dialog layout. i think this is final, but it’s not connected to any backend yet.
first connection of the nakamura dialogue box to the backend. the squaring operations work! try highlighting the d1 h20 differential in the May SS and tinkering around with the values in the dialog.  very satisfying!
