Managing data files in problematic.
Once a data file is uploaded into eQa, existing cell data can be edited in eQa. However, rows and columns can't be added or deleted.
The user may have lost, changed or damaged the original local csv that was used for the first upload.
Since there is not full editing within eQa, provide a mechanism to export / download the data file from eQa to the local computer so it can be edited.
Then it can replace the existing file in eQa.
