#1597, #1609, #1640:

  • Corrected TableFileParser to handle empty rows correctly.
  • Refactored DataSet to store values in List<List> instead of a two-dimensional array.
  • Enable importing and storing string and datetime values.
  • Changed data access methods in dataset and adapted all concerning classes.
  • Changed interpreter to store the variable values for all rows during the compilation step.
