* Originally made by WordPress part of WordPress/Importer.
* https://plugins.trac.wordpress.org/browser/wordpress-importer/trunk/class-wp-import.php
*
* What was done:
* Reformat of the code.
* Changed text domain.
* Changed methods visibility.
* Changed method from `get_authors_from_import` to `set_authors_from_import`.
* Changed method from `get_author_mapping` to `set_author_mapping`.
* Removed use of '$_POST' the input 'options' will be passed via constructor args.
* Removed echos, UI and print methods, all echos replaced with `$this->output` append.
* Removed `die` ( exit(s) ).
