EDIT

This framework should allow to analyze import data before running the import.

This should include

• analyzeWorkbook(): ananlyzes the overall Workbook structure (obligatory worksheets with correct names, tables which are not required, ...)
• analyzeWorksheetStructure(): which analyzes the existing columns (obligatory columns, facultative columns, columns not in use, ...)
• analyzeData: which analyzes the data in the worksheet(s) on correctness, this includes
  • test new data: is the new data correctly formatted so it can be imported
    
  • test persistent data: e.g. do taxon UUIDs match with existing accepted taxa
  • ...
    

The framework in general should only work for csv data.

The result should be generic so it can be used for any table based imports (or even for non-table based imports).
The result should distinguish data which is generally impossible to import (e.g. a required column could not be found), data which looses certain records during import and data which has slightly incorrect import result (e.g. 1 not required field in a record can not be imported).
