itaps-parallel ITAPS for 2D meshes

[Tim Tautges]

Answering Karen's question, yes, these should be types, not dimensions, 
though for most I think the two are synonymous.

Regarding multiple dimensions, we could allow multiple ghost dimensions, 
or we could say that subsequent calls build on the existing bridge 
interactions if they're not reset.
