Fills the map with the paramters for the given subdetector.
Each vector "v" holds the parameters for the layers/rings, if the vector has only one parameter all the layers/rings get that parameter.
The only other possibility is that the number of parameters equals the number of layers, otherwise an exception of type "Configuration" will be thrown.
