# loaded the correction translation is applied to create the "real" simple

# Although this seems odd it is necessary so that any PythonAlgorithm 
# can call any other PythonAlgorithm through the simple API mechanism. If left 
# to the simple import mechanism then plugins that are loaded later cannot
# be seen by the earlier ones (chicken & the egg essentially).
