Asotin weir moved

[KevinSee]

In the Asotin, in 2010 and 2011, the Asotin weir (ASOTIC) was located upstream of the instream array ACB. After that, it has been placed downstream of ACB. DABOM should reverse the ASOTIC and ACB nodes if being run in 2010 and 2011.

Given the generic writeDABOM model now, I think this change can be accommodated as long as the parent-child table is correct for a given year. I don't think the location (lat/long) of ASOTIC differs between 2010/2011 and subsequent years, so it is up to the user to ensure it is correct. A simple use of editParentChild() should do the trick.
