 /**
  * This action is for importing a single CSV file into a single database table.
  * It guides the user through the four stages of importing:
  * uploading, field matching, previewing, and doing the actual import.
  * All of the actual work is done in [WebDB_File_CSV].
  *
  * 1. In the first stage, a CSV file is **uploaded**, validated, and moved to a temporary directory.
  *    The file is then accessed from this location in the subsequent stages of importing,
  *    and only deleted upon either successful import or the user cancelling the process.
  *    (The 'id' parameter of this action is the identifier for the uploaded file.)
  * 2. Once a valid CSV file has been uploaded,
  *    its colums are presented to the user to be **matched** to those in the database table.
  *    The columns from the database are presented first and the CSV columns are matched to these,
  *    rather than vice versa,
  *    because this way the user sees immediately what columns are available to be imported into.
  * 3. The column matches are then used to produce a **preview** of what will be added to and/or changed in the database.
  *    All columns from the database are shown (regardless of whether they were in the import) and all rows of the import.
  *    If a column is not present in the import the database will (obviously) use the default value if there is one;
  *    this will be shown in the preview.
  * 4. When the user accepts the preview, the actual **import** of data is carried out.
  *    Rows are saved to the database using the usual [WebDB_DBMS_Table::save()](api/Webdb_DBMS_Table#save_row),
  *    and a message presented to the user to indicate successful completion.
  *
  * @return void
