Couple of critical errors in running 'cce' example

[ftroeman]

Running the 'cce' example using the latest implementation of abcEconomics produces an AttributeError: 'Simulation' object has no attribute 'declare_service'. Looking at 'init.py' in the source code for the latest abcEconomics implementation, the Simulation class no longer has the 'declare_service()' function. The latest documentations referred to all indicate that declare_service() is still a usable function. Is there a change in the way services are implemented?

Bypassing the 'declare_service()' functions, I find that the 'build_agents()' function also produces a critical error for each agent that we are trying to build:
` File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/abce/singleprocess.py", line 45, in insert_or_append
agent.init(**ChainMap(simulation_parameters, ap))

TypeError: init() missing 14 required positional arguments: 'num_firms', 'price_stickiness', 'network_weight_stickiness', 'dividends_percent', 'capital_types', 'output_tax_shares', 'production_functions', 'outputs', 'money', 'sam', 'tax_change_time', 'carbon_prod', 'carbon_tax', and 'tax'`

Does the 'cce' code only work with specific, older versions of abce/abcEconomics?

Would greatly appreciate your advice in resolving these issues!
