MKS Integrity implementation for Maven's AbstractExportCommand
Since the IntegrityCheckoutCommand creates a fresh Sandbox in the checkoutDirectory, it does not make sense for the IntegrityExportCommand to essentially do the same thing.
Hence, this command does not create a Sandbox, instead the entire project contents are exported to the exportDirectory using the 'si projectco' command.
This gives the user the option of exporting a fresh copy of the repository void of any project.pj files
