record_linkage_example - Errors after training when saving file

[jameskaris]

Using Python 3.7 on Centos 7 workstation.

Run the sample file: record_linkage_example.py

After training first 12 records, press "f" for finished, and the system errors.

Looks like a small typo, the new API for writing settings as of dedupe 2.0 should be linker.write_settings(sf).
