Rework excel file / sheet / columns and related object names

[Felixmil]

The names are really not homogeneous and make it kind of hard to use in code, other applications and also not always very clear in the excel files.

For example we sometime use Id or Name as unique identifier, I would change all to Id.

Sometimes camelCase is used, other just regular text like Container Path

in ProjectConfiguration, scenarios is refered as scenarioDefinitionFile, individuals as individualsFile while the excel file for models is called paramsFile.

I think this deserve some kind or rework. Maybe some rules need to be defined first ?

If we do this (and I agree that we should), we should provide a script that converts old excel files to the new structure.
