Groovy script to list users in a group, by last login

[Stephen_Hayden]

Was wondering if there's an obvious place to look for this, wasn't having much success w/ documentation or older questions due to changes in the tool(s) breaking some older partial examples. Looking to use something like this to help prune Service Desk permissions a bit in Jira 7.3.  Would like to feed it a group and then will take the results (username, last login and a couple custom fields) and parse them in excel or something.

Thanks in advance for the thoughts or suggestions. Thanks!
