Usage instructions:
1) create an "importer" instance inside the folder that will contain the batch-created objects
2) follow the step based wizard (schematas):
   - give a title to the importer (you may have multiple importers around)
   - choose the portal type of the objects you want to import
   - upload/paste a csv formatted file *headers must be present* (see example/sample_csv)
   - map csv fields to AT fields, if you don't want to use a particular csv field choose "Not used";
     if you get an error in this step it is most likely that the csv file previously uploaded is not valid.
     Here you can also choose a prefix to use for the imported objects.
   - start the batch import and examine log for details
3) check out the imported objects

To test it out it is possible to use the Sample_AT and sample_csv provided in example folder.
To use Sample_AT it must be copied on the product folder and must be included in init.py.
