Grid Proxy/Credential set up

Check list for making sure your grid-credential files and setup is correct:

1. Make sure you have non-expired grid credential files in your .globus directory
1. usercert.pem
2. userkey.pem
2. Be sure you have your proxy on myproxy.teragrid.org (or wherever you need to keep it)
1. myproxy-init -s myproxy.teragrid.org
3. Make sure your ".globus/certificates" folder has the right certificates files, get them from your CA's certificates folder and makes sure you have all of the ones listed in the CA's folder.
4. Remove any ".r0" files in your ".globus/certificates" folder. These are unnecessary.
