ENH: Addition of a median image filter to allow the user to smooth the output label map.
ENH: Addition of an option to enlarge the bounding box computed using the input mesh.
STYLE: Improvement indentation and comments of the source code.
ENH: Printing median filter radius size when using option verbose
ENH: Only print bounding box information if option verbose is selected
ENH: Output label map saved in correct space (LPS)

VTK coordinates are in RAS
ITK coordinates are in LPS
We need to convert from RAS to LPS when the output label map is saved using ITK.
