Thank you for asking this question. If you go back to the instructions for posting questions on this site, you will see a couple of example questions designed to illustrate what is a good question and what is a bad question. This question is a much improved example of a bad question that is almost guaranteed not to garner a helpful response of any kind. I'm going to write to Igor and propose that he replace the current bad example with your submission. Congratulations.
Please go back and read the instructions. Read them several times if necessary. Then follow the instructions.
