Hello,

make `SimplecticGraph` a deprecated alias to `SimplecticPolarGraph`?

Works for me.

+1. Though I beware of wikipedia now. I have experienced how hard it is to
fight the whims of those who are "in charge" of some pages...

dual polar graphs complete, one should add orthogonal dual polar graphs.
Reorganization can indeed wait, but must not forget to address the
"SymplecticDualPolarGraph" vs "SymplecticGraph" issue.
