TR = graft(TR1,B) TR = graft(TR1,B,NM)
graft adds root branch B onto a tree variable TR1 (previously created by tree or mksys). If TR1 has N branches, then the numerical index of the new branch is N+1; and the numerical indices of other root branches are unchanged.
The string name NM, if present, becomes the name of the new root branch.
