Update Build Tree method to not display entire subroutine

[Jon McBee]

The Build Tree method should only show the top level of the subroutine and it’s attributes, not the entire subroutine. This ask comes from the need to have a graphical editor for the sequence, where the expectation is that a user should not be able to edit the contents of a subroutine while editing it’s calling routine.
