# This class is the high level wrapper that provides
# access to cloud-init objects without exposing the stage objects
# to handler and or module manipulation. It allows for cloud
# init to restrict what those types of user facing code may see
# and or adjust (which helps avoid code messing with each other)
#
# It also provides util functions that avoid having to know
# how to get a certain member from this submembers as well
# as providing a backwards compatible object that can be maintained
# while the stages/other objects can be worked on independently...
