Better Description?

Issue Summary

This looks like a useful module, but I'm concerned that most administrators won't have any idea what it does based on the current description.

Think you could add an example use situation or two? How 'bout a quick explanation of what sessions are.

I haven't messed with the module at all, so I don't know if this is true or not, but here's a draft:

The session-limit module is allows administrators to limit the number of simultaneous sessions a user may have.

A session is created for each browser that a user uses to log in, so this will essentially have the effect of logging a user out of their other browsers when they log in. So assuming that the session limit is 1, if a user is logged in to a Drupal site from their work computer and they log in from their home computer, their work computer will be automatically logged out of the site.

Just a thought. Feel free to ignore. :-)
