title: How to call a cpdef method from C
body: <p>I have a public class with a method defined with cpdef. According to cython documentation, this can be called from C. However the generated header does not have any C/C++ functions/method generated for this. </p>
  
  <pre><code>cdef public class Model[type ModelType, object Model]:                                                           
    cdef ModelContext *modelContext                                                                                
    cpdef calculate(self):                                                                                           
      print 'calculate called on Modell' 
  </code></pre>
