Description (last modified by bump)

This currently breaks: 

sage: B=KirillovReshetikhinCrystal(['D',5,1], 3,1)
sage: B[0].e(0)

This has to do with the method intermediate_shape for plus/minus diagrams.

After the patch, passes sage -testall.

Fixes the crash mentioned in the Description.

Includes doctest.

Apparently the intermediate_shape method of PMDiagram presumed that self.n was 2.

This one-line fix is obviously correct.
