[Insight-developers] Is MeshKComplex.cxx right?

Having now (belatedly) looked at itkMeshTest.cxx, it looks like one also 
needs to:

3. Call AddUsingCell on the given boundary cell to record that a 
particular cell has it as a boundary.

Should all of this be indicated in the User's Guide?  Do you want me to 
do that?

This is answered by itkMeshTest.cxx.  I'm sorry I didn't check that 
before asking the question.
