Using wfdb within another package

[Scoodood]

wfdb-python/wfdb/processing/basic.py

Line 4 in 6f14dba

from wfdb import Annotation

The line above is causing problem when I use wfdb within another package such as this one

dbdriver\
   __init__.py
   wfdb\
   xyz\

Here is my fixed. Is this a better way?

from ..readwrite.annotations import Annotation
