This setting determines how the package is included in the course. There are up to 4 options:

* Uploaded package - Enables a SCORM package to be chosen via the file picker
* External SCORM manifest - Enables an imsmanifest.xml URL to be specified. Note: If the URL has a different domain name than your site, then "Downloaded package" is a better option, since otherwise grades are not saved.
* Downloaded package - Enables a package URL to be specified. The package will be unzipped and saved locally, and updated when the external SCORM package is updated.
* External AICC URL - this URL is the launch URL for a single AICC Activity.  A psuedo package will be constructed around this.
