Experimental implementation of Chunk Importer for October CMS. Based on October's original ImportExport behavior.
This plugin comes with test models and controllers, so it's up and ready for testing. Take Test CSV file from /assets folder and try to import some data.
Now import process is splitted into chunks. Each chunk processes 50 records at a time, each chunk is a new AJAX request, and that's how progress bar is being updated.
There's also a Import Log side menu, where You can find user, who imported particular file, imported file name and date it was imported at.
