"""initCheckerBoardFunction
Generates two classes similar to a chekerBoard table. One classe would be in the same position
as the black part of the board and the second in the white one
Parameters:
INPUT:
Ndata: number of instance of each quadrant
nx: number of quadrants in x
ny: number of quadrants in y
delta: scramble factor, a lower delta means more entangled classes
OUTPUT:
cls1, cls2 : objects from classData with encapsulates all data from a given sub-class.

myData = LoadData.clsWorkingData()
cls1, cls2 = myData.initCheckerBoardFunction(50,2,2,0.5)
