Upload wizard cannot deduce csv structure

Description of the issue

The upload wizard is helpful when uploading csv file, however if a table does not yet exist, its structure has to be created by hand and then created and only if everything goes well, the csv can be uploaded into the new table. The OEP should be able to help with this process.

Ideas of solution

Dropping a csv file into the page should prompt an analysis of the first few lines, taking column names and inferring data types. This information should either suffice to create a table or get there with minimal further user input. Maybe OMI can assist with this.
