initializeStaticVariables

public static void initializeStaticVariables()

Initialize the static variables such as grandSum. This may have to be called when different classes utilize this class at same time.

setRelativeAccuracy

public static void setRelativeAccuracy(double epsilon)

Change the relative accuracy in the inegration
