BandAttStats function parameters

[Alpesh]

Hello Sir,

In Raster GIS Module, 

In following  function

rsgislib.rastergis.BandAttStats(band, minField=None, maxField=None, sumField=None, stdDevField=None, meanField=None )

it has only five attribute parameters.

 I want to add one more parameters in it,    for example: 'Mode' 

I have seen rastergis    __init__.py file 

In that file

 class  BandAttStats : 

 def __init__( self, band, minField=None, maxField=None, sumField=None, stdDevField=None, meanField=None ) :

      self.band = band

     self. minField = minField

     self. maxField = maxField

     self. sumField = sumField

     self. stdDevField = stdDevField

     self. meanField = meanField  

I could not find the where exactly  meanField, stdDevField  equation is defined.

How can I add more parameters in this "rsgislib.rastergis.BandAttStats"  function ?

I will be  very thankful for your valuable reply.
