Please rename lib/couchbase module so that it doesn't conflict with public sdk

Hey Deep, believe you have many tests relying on the couchbase.py module. Problem is whenever I have public couchbase sdk installed and try to use anything from testrunner that relies on rest_client, I get the following error:

File "../lib/membase/api/rest_client.py", line 8, in <module>
from couchbase.document import DesignDocument, View
ImportError: No module named document

In the past I've done workaround by modifying sys.path to import local couchbase module first. But now I have a complicated situation where this is no longer working.
Will be great to find another name for this: 'lib/couchbaseinternal' or 'lib/rest_couchbase' ?
