This tools helpers
------
    The version number is somewhat special because the evolution of the
    rdata's format is non-linear.
    There may be different branches, each evolving separatly.
    To reflect these branches's diversions, there may be a prepended
    branch name following this format:
        major.minor.patch-branch_name
    Like this, we can process rdata with the same tool, and output
    rdata formated differently, for each tool.


  - enriched_rdata:
    - Description: flag created by that tool to tell it was enriched.
    - Retrieval method: enriched_rdata <- TRUE

  - enriched_rdata_version:
    - Description: A flag created by that tool to tell which version of
        this tool has enriched the rdata.
    - Retrieval method: enriched_rdata_version <- sprintf(\"%s\", ENRICHED_RDATA_VERSION)

  - enriched_rdata_doc:
    - Description: Contains the documentation string.

Data from original mzxml file
------

Data taken from incoming rdata
------
  - variableMetadata:
    - Description: Unmodified copy of variableMetadata from incoming rdata.
    - Retrieval method: rdata_file$variableMetadata

  - process_params:
    - Description: Those are the processing parameters values from the
        curent rdata. They have been simplified to allow easy access like:

            if (params[[\"xfunction\"]] == \"annotatediff\") {
                process_peak_picking_params(params)
            }
        }
    - Retrieval method:
