Import API/SPI provides the import workflow to import data form any support.
            API is providing a secure workflow, from importers that connects to
            the data source (files, databases, wizards...) to the processors that
            append imported data to the workspace. It is based on the
            Container interface, that has a loading and unloading
            sub-interface. Importers are loading the container, then the controller
            is checking it's consistency and finally processors are unloading it.
        
            See org.gephi.io.importer.spi package to know how to define
            new data importers.
