Got rid of the "Dao.Procedural" module, which I had stopped using
probably a year ago. I had forgot it was still there, and the
"Dao.Interpreter" module depended on it for just one function,
'Dao.Interpreter.recurseGetAllStrings', which continued to make use of
the functions in "Dao.Procedural". I re-wrote
'Dao.Interpreter.recurseGetAllStrings' and got rid of the import
statement, which made it safe to remove the source file for
"Dao.Procedural".
