-store in the importer account the temporary credentials needed
during setup.
-store in the importer account the access token, and the access token
secret, and guard them. They are needed at the end of the setup (to get
the user's info) and all along a run.
-not share the same oauth.Client with the whole package. Create a new
one everytime it's needed in the setup. Create a new one at the beginning
of a run too, and it's ok to reuse it all along, since it's used
read-only.
