append()

AFPToFMCDBCreate.AFPDBDict.append	(		self,
			stationID,

A function that overwrites one slice of the ToF parameters in the dictionary. Local ToF parameters have to have both trainID and barID defined, Vertex ToF parameters neither.

savePayload()

A function to transform the dictionary to JSON and save it in IOV from 0 to infinity; technically, upper limits are undefined and the maximum value (until beginning of a next entry) is used.
