@package rlisetup.py

@brief   GUI per r.li.setup module

Classes:
 - RLiSetupFrame (first frame to show existing conf file and choose some
                 operation)
 - RLIWizard (the main wizard)
 - FirstPage (first page of wizard, choose name of conf file, raster, vector,
              sampling region)
 - Keyboard (page to insert region areas from keyboard)
 - SamplingAreas (define sampling area)
 - SummaryPage (show choosen options)
