libzdl

Since a lot of ZDL code is redundant, and probably could be used in other ZDL projects, I think it makes sense to provide my backbone ZDL code as a library for others to use. I plan on both releasing the native C++ and a C interface.

Perhaps I’ll incorporate it into Bio’s ZDL as well, because that readINI stuff is wayyy to funky.

Also, I hope to get something to show in terms of ZDL this weekend, even if it is a halfbrained jumble of that that hardly works - it’s more than what I got now.
