Differences in output.
    * The histogram plot show slightly different values to
      the original library. This could be for one of 2 reasons.
        1. An issue with selecting the results into ExtractedData
           objects.
        2. The original library plotted incorrect results potentially
           including NaN as a value. This would have provided larger
           datasets than the re-work which explicitly deletes NaN
           values.

    * Added reset method to change index on small dataframes
    * Frames are now merged in on a copy with the column names on the original frame reset post merge
