It should be noted that SWIG implements #if/#endif preprocessing, so it should 
be possible to "wrap" Python-specific pieces with #if/#endif and use other 
#if/#endif blocks for the Node.js specific pieces that replace the 
Python-specific pieces.  This would allow using the *same* .i files for both, 
just with different options to the swig command.
