README instructions for user-specified YAML config incorrect

[ianthomas23]

If I follow the instructions for user-specified YAML config from the README, i.e. create the suggested my_services.yaml and then run

python mapshader/flask_app.py -f my_services.yaml

I get

File "/home/iant/github/mapshader/mapshader/services.py", line 242, in parse_sources
    for service_type in source['service_types']:
KeyError: 'service_types'

If I add the following to my_services.yaml (I am guessing here)

sources:
  - name: Elevation
    <existing lines>
    service_types:
      - tile

then I get passed the previous error but see

AssertionError: View function mapping is overwriting an existing endpoint function: Elevation tile

This occurs with both master and the 0.0.9 release.

So there is some inconsistency between the code and the README.

Hey @ianthomas23! I created a PR (#95) to fix the YAML config example. Could you try to use the new one?

@giancastro Yes, that works perfectly for me. Thanks very much!
