Topic: version 4.7w

Bugfix: Fixed bug in using the option NLDPARITY (and in the default behavior). Since by default this OPTION is ON, the output will be slightly different as compared to the previous version.
(Note: This does not affect the rate results published in Mocelj et al. (2007) as this bug was introduced later.)

Additionally, minor changes in the code were made (streamlining, does not affect the output but will improve performance and ease of maintenance).
