Tidy real-to-complex FFT -- forward and inverse have different arguments, so make them separate functions; document

     for (int i = 0; i < fftSize; ++i) inputData[i] = inframe[i];
 
     window->cut(inputData);
   
     /* Calculate the fft on the input frame */
-    fft->process(0, inputData, realOut, imagOut);
+    fft->forward(inputData, realOut, imagOut);
 
     free(inputData);
 
     return process(realOut, imagOut, outceps);
