Run directories about parsl

[danielskatz]

The idea seems good, but some details are not clear to me:

1. What is NNN?
2. Is it always three characters?

1. I should have specified this as run[0-9][0-9][0-9] (Run followed by three digits).
2. In swift we had 3 digits. We need to guess here in terms of how many instances we expect users to run.

Specifically the logic here would be that the first run would have the dir run000 and every subsequent run would increment the run number by 1. The only reason to use runNNN is that it looks nicer with the number padded with 0's when ls'ing the directories.

[danielskatz]

what happens if there are more than 1000 runs?

[yadudoc]

run000 -> run001 - > ... run999 -> run1000.
It's padded to 3 positions.

[danielskatz]

sounds reasonable

From Slack, @danielskatz suggested a top directory with the numbered ones underneath, and now we're all in agreement on:

runinfo/000
runinfo/001
...

Great! I'll add this to the multisite branch that needs this functionality.

This functionality has now been merged to master from branch:multisite.
