This class defines services which permit to access Data issued from a File, in a form which does not depend of physical format : thus, each Record has an attached ParamList (to be managed) and resulting Entity.
Each Interface defines its own FileReaderData : on one hand by defining deferred methods given here, on the other hand by describing literal data and their accesses, with the help of basic classes such as String, Array1OfString, etc...
FileReaderData is used by a FileReaderTool, which is also specific of each Norm, to read an InterfaceModel of the Norm FileReaderData inherits TShared to be accessed by Handle : this allows FileReaderTool to define more easily the specific methods, and improves memory management.

Initializes arrays of Entities and of ParamLists attached to registered records <nbr> must be the maximum number of records to get (no way to extend it at run-time) : count entities and sub-entities ... <npar> is the total count of parameters (if it is not exact, it will be extented as necessary)
Hence, to each record can be bound an Entity and a list of Parameters. Each kind of FileReaderData can add other data, by having them in parallel (other arrays with same sizes) Else, it must manage binding between items and their data
