Release tarballs are huge

The tarball for 2.1.1 is almost 60 MB, perhaps the CSV test files can be computed on demand instead of including them in the repo?

good call. there's just a few really big, and they're for profiling rather than unit test. and yes the biggies were autogenerated. ;)

i'll look into this.

20f606d brings it down. I'll take another crack at one of the larger remaining data files, which is used as a doc example.

Thank you!!!
