Flags:
- -e
- Output map 'edge' of edges given a '1' in r.le.para/edge file
- -u
- Output maps 'units_x' with sampling units for each scale x

- Output map 'zscores' with standardized scores
- --help
- Print usage summary
- --verbose
- Verbose module output
- --quiet
- Quiet module output
- --ui
- Force launching GUI dialog
