Python UDF Example

On this page (https://docs.couchbase.com/server/current/analytics/9_udf.html#external-function-examples), can we highlight the module, class, method & analytics library? This tripped me up when I was trying to deploy a Python UDF. 

module: sentiment_mod

class: sent_model

method: sentiment

analytics library: pylib

Another option would be to refer to appendix 5 for more details because this example is completely understood when seen together with it.
