# History:
# 	Stan Smith 2013-11-01 original script.
#   Stan Smith 2014-07-08 modify require statements to function in RubyGem structure
#   Stan Smith 2014-12-12 refactored to handle namespacing readers and writers
#   Stan Smith 2015-06-11 change all codelists to use 'class_codelist' method
#   Stan Smith 2015-06-22 replace global ($response) with passed in object (responseObj)
#   Stan Smith 2015-07-14 refactored to make iso19110 independent of iso19115_2 classes
#   Stan Smith 2015-07-14 refactored to eliminate namespace globals $WriterNS and $IsoNS
