Sample dictionnary generation breaks when xsec not documented

	print ('self.para.gridpacklist[processhad][3] ',self.para.gridpacklist[processhad][3])
	print ('self.para.gridpacklist[processhad][4] ',self.para.gridpacklist[processhad][4])
	xsec = float(self.para.gridpacklist[processhad][3])

The xsec variable can't be defined when no value of the cross-section is included in param_FCCee.py, and the code crashes in such cases. A quick fix could be to include a dummy value for cross-sections for when the read string is empty. Would that be desirable (I can see interest in not generating the dictionnary, as a reminder to include the missing xsec)?
