Referring to attached image, is there some way for a GLMTreePresentation
to align one column vertically. I want to transform what I have in the
top part, into what I have mocked up in the bottom part.
I can't see anything related in GLMBasicExamples. I see there is a
GLMMorphTreeColumn class but preliminary digging doesn't reveal to me
how this fits into things.
cheers, Ben
