[MOAB-dev] Range contiguity method

[Patrick Shriwise]

Hi Vijay,

After some exploring, I saw the psize method. That would do the trick.

Perhaps a quicker way would be to check that there is no more than one 
pair in the Range rather than iterating over them all, but there 
probably aren't many pairs in Ranges in practice. Is that right?

Cheers,
