We need to determine whether to use TFile/TKey binary file format or not.
We need to determine whether to use (part of) TFile/TKey code.
These are independent questions.
What advantages would were have from creating a new file format?
What is the advantage of re-implementing TKey and TFile?
We will need to get rid of libCling dependency, might need to split functionality and reuse for TFile, RFile.
Ingredients: object ownership and directory hierarchy representation in memory will change for RFile. Little endian storage has an effect.
