//  RBTT Exchange Rates Processing v1.0
//		- written by Rob Robichaud / April 20th 2010
//		- detects current country
//		- detects if output is required (looks for right nav id or full table id)
//		- processes appropriate output for right nav or full table
//
//  RBTT Exchange Rates Processing v1.1
//		- Updated by Rob Robichaud /July 29th 2010
//		- added logic to swap '$' with 'Afl.' for Aruba, 'ANG' for Curacao and Bonaire, 
//		  'SRD' for Suriname, 'ANG' for St. Maarten/Saba on Full Rates Table.
//		  for the right nav we simply remove the '$' symbol.
//
//	Dependencies:
//		- jQuery v1.4.1
//		- correct XML source paths and country association (array)
//		- correct output IDs
