Convert the config JSON to a YAML file

[swfarnsworth]

YAML files appear to be better suited for storing configuration data than JSON.

-Config file -- Should be converted to a YAML file.
-Config reader -- This should probably be deleted and we can let a library like PyYAML handle what this module is for.

[vmdhhh]

We can convert the JSON to YAML and just modify the Config reader to read YAML config rather than deleting it right?
What do you think @swfarnsworth ?

[swfarnsworth]

@vmdhhh That's certainly an option, though the config reader that we implemented isn't widely used and if the PyYAML library does everything we'd need (and it's possible that it doesn't--I haven't done that exploration), I figure that in general we should reduce how much meta-functionality this package has.

[vmdhhh]

@swfarnsworth For now, AFAIK the Config reader module is only getting used in Pipeline components and Get Metamap .
So changing config JSON to YAML and including pyYAML into Pipeline components and Get Metamap would be enough right?
If yes, I can try to do it. Let me know.
