Thanks for the post, Dixiecat.

I'm sorry for the delay in this project. I'm continuing to work on this, but it is taking a back seat for the foreseeable future. My father has terminal cancer. I'm also interviewing for jobs. Between the two, there isn't a lot of time at the moment.

Sorry for the inconvenience to everyone. Continue on in my absence, if you wish. I'll work on the pattern and post again when I get to a substantive point.
