Added a section with a collection of references on intersection laws for black D-branes ending on black NS5-branes. Then I spelled out the case of D6-branes in some detail, collecting the relevant diagrams from the reference EGKRS00, and used this to identify the corresponding M-theory lift by the M5-brane near horizon ADE-orbifolds of the 4-sphere.

Expanded discussion of D-branes suspended between NS5-branes a bit more. In particular cross-linked with Hanany-Witten construction and geometric engineering of quantum field theory.

added section on NS5 half-branes. Copied the same material also over to a section Intersection of D6s with O8s at intersecting D-brane models

added more references on the NS5/D4/D2 bound states, and also on the resulting ODp-theory on the NS5 worldvolume

had trouble finding more recent references on the NS5/D4/D2 bound states, but now somebody kindly points out one more to me, which I have added to the entry:
