Check syntax and content of patterns files

[cmungall]

I don't think this is correct:

https://github.com/obophenotype/chiro/blob/master/patterns/biologicalRole_modulatorOf_x.yaml

The way to test is run through dosdp-tools query, to generate TSV. Maybe @balhoff can help?

We should also have the patterns folder in src as is conventional, see ODK

I moved the folder

@balhoff could you help test if the patterns are correct? Thank you!
