title: Python: ImportError: cannot import name misc
body: <p>I was trying to use the wafo (version 0.1.2) package in python (version 2.7.10) in windows system. I used the installer from this link: <a href="https://pypi.python.org/pypi/wafo/0.1.2" rel="nofollow">https://pypi.python.org/pypi/wafo/0.1.2</a> to install it. Then I tried to test the example script from the user manual:    </p>
  
  <pre><code>from scipy import *
  from pylab import *
  import wafo.spectrum.models as wsm
  import matplotlib
  S = wsm.Torsethaugen(Hm0=6, Tp=8);
  S1 = S.tospecdata()
  S1.plot()
  show()
  </code></pre>
  
  <p>There several errors occurred like "ImportError: No module named lib.six" occurred. But I fixed them by importing the modules needed. Finally I got the following error messages:</p>
  
  <pre><code>Traceback (most recent call last):
  File "&lt;tmp 1&gt;", line 3, in &lt;module&gt;
  import wafo.spectrum.models as wsm
  File "c:\python27\lib\site-packages\wafo-0.1.2-py2.7.egg\wafo\__init__.py", line 4, in &lt;module&gt;
  from . import misc
  ImportError: cannot import name misc
  </code></pre>
  
  <p>I tried to google but could not find any remedied. Could anyone give me a solution on this error? Thank you!</p>
