Error running ISO example script

[rsignell-usgs]

We installed using

conda install -c conda-forge wicken libiconv -y 

and tried running the ISO script:

$ python example_iso_script.py

which produced:

Traceback (most recent call last):
  File "/home/jovyan/github/wicken/wicken/dogma.py", line 64, in __set__
    dogma._set(self.teaching, value, self.options)
  File "/home/jovyan/github/wicken/wicken/xml_dogma.py", line 83, in _set
    raise NotImplementedError()
NotImplementedError

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "example_iso_script.py", line 48, in <module>
    data_object.service_provider_name = 'David Stuebe'
  File "/home/jovyan/github/wicken/wicken/dogma.py", line 131, in obj_setter
    super(Dogma, self).__setattr__(k, v)
  File "/home/jovyan/github/wicken/wicken/dogma.py", line 70, in __set__
    raise DogmaGetterSetterException(exception_string)
wicken.exceptions.DogmaGetterSetterException: Error setting the 'service_provider_name' property of the class 'Iso19115XmlDogma'
Set operation raised exception: 'NotImplementedError()'

@dstuebe, any ideas?
