Re: Tracking tasks

[Elton Smith <elton@jlab.org>]

HI David,

We should add that to the list.

Also, I forgot to include the possibility of using two straws in the
close-pack design. According to Curtis this would require two types of
inserts, but most of the pieces remain the same.

Thanks, Elton.
