SQL Server User Security Report Script

I needed a way to report on what permissions are assigned to a user on SQL Server. For added bonus I wanted to be able to specify a group and then list out all the users in that group with their permissions. As a double added bonus I wanted to set a flag so you could generate the DDL for a new user in case you want to duplicate the permissions to a new user or group.

Bingo. First version here. I am sure there are several versions of this on the web, but at the moment this one is working well for me.
