No such file or directory: b.csv when I run it

[RossBoylan]

Joanne also mentioned seeing errors about b.csv sometimes. Here's what I got:

Analysis: this is the result of attempting to run iteration 1 before running iteration 0, which creates many of the essential files and directories. The command is not, as I thought, mc run <first iteration> <# of iterations> but, as I documented mc run <# of iterations> <first iteration>!

So my command attempted to run 0 iterations starting with iteration 1, which did cause iteration 1 to run (seems as if it shouldn't have....).

Joanne thinks it is likely that the problems she ran into had a similar source.

At one level, this is not a bug at all but user error.

However, it raises some general questions about how to handle incomplete runs, more fully expanded in #5.

More narrowly, is there a usability problem here?

And why did a request for 0 iterations produce any activity?

Because of these lingering issues, I'm leaving this issue open, although the immediate problem is resolved.
