Switching default date from Submitted to Issued, new DOI update example

This release switches how the default TIND date is mapped (previously "Submitted" and now "Issued") and pulls the publication year from the Issued date. It also includes an example script for updating dates based on info from DataCite. The get_metadata function adds an option to pass back contributor emails, even though this isn't part of the DataCite schema.

Reduce logging, update dates, and adjust write API

This release reduces the number of print log statements. It standardizes how dates are returned (relying on the DataCite dates more and minimizing the TIND specific metadata) and makes a small adjustment to the write API to match changes from TIND. There are also a couple more example scripts.
