+   Flags/methods for returning states.
+
+   The SWIG conversion methods, as ConvertPtr, return an integer
+   that tells if the conversion was successful or not. And if not,
+   an error code can be returned (see swigerrors.swg for the codes).
+
+   Use the following macros/flags to set or process the returning
+   states.
+
+   In old versions of SWIG, code such as the following was usually written:
+
+     if (SWIG_ConvertPtr(obj,vptr,ty.flags) != -1) {
+       // success code
+     } else {
+       //fail code
+     }
+
+   Now you can be more explicit:
+
+    int res = SWIG_ConvertPtr(obj,vptr,ty.flags);
+    if (SWIG_IsOK(res)) {
+      // success code
+    } else {
+      // fail code
+    }
+
+   which is the same really, but now you can also do
+
+    Type *ptr;
+    int res = SWIG_ConvertPtr(obj,(void **)(&ptr),ty.flags);
+    if (SWIG_IsOK(res)) {
+      // success code
+      if (SWIG_IsNewObj(res) {
+        ...
+	delete *ptr;
+      } else {
+        ...
+      }
+    } else {
+      // fail code
+    }
+
+   I.e., now SWIG_ConvertPtr can return new objects and you can
+   identify the case and take care of the deallocation. Of course that
+   also requires SWIG_ConvertPtr to return new result values, such as
+
+      int SWIG_ConvertPtr(obj, ptr,...) {
+        if (<obj is ok>) {
+          if (<need new object>) {
+            *ptr = <ptr to new allocated object>;
+            return SWIG_NEWOBJ;
+          } else {
+            *ptr = <ptr to old object>;
+            return SWIG_OLDOBJ;
+          }
+        } else {
+          return SWIG_BADOBJ;
+        }
+      }
+
+   Of course, returning the plain '0(success)/-1(fail)' still works, but you can be
+   more explicit by returning SWIG_BADOBJ, SWIG_ERROR or any of the
+   SWIG errors code.
+
+   Finally, if the SWIG_CASTRANK_MODE is enabled, the result code
+   allows to return the 'cast rank', for example, if you have this
+
+       int food(double)
+       int fooi(int);
+
+   and you call
+
+      food(1)   // cast rank '1'  (1 -> 1.0)
+      fooi(1)   // cast rank '0'
+
+   just use the SWIG_AddCast()/SWIG_CheckState()

+ * Type initialization:
+ * This problem is tough by the requirement that no dynamic
+ * memory is used. Also, since swig_type_info structures store pointers to
+ * swig_cast_info structures and swig_cast_info structures store pointers back
+ * to swig_type_info structures, we need some lookup code at initialization.
+ * The idea is that swig generates all the structures that are needed.
+ * The runtime then collects these partially filled structures.
+ * The SWIG_InitializeModule function takes these initial arrays out of
+ * swig_module, and does all the lookup, filling in the swig_module.types
+ * array with the correct data and linking the correct swig_cast_info
+ * structures together.
+ *
+ * The generated swig_type_info structures are assigned statically to an initial
+ * array. We just loop through that array, and handle each type individually.
+ * First we lookup if this type has been already loaded, and if so, use the
+ * loaded structure instead of the generated one. Then we have to fill in the
+ * cast linked list. The cast data is initially stored in something like a
+ * two-dimensional array. Each row corresponds to a type (there are the same
+ * number of rows as there are in the swig_type_initial array). Each entry in
+ * a column is one of the swig_cast_info structures for that type.
+ * The cast_initial array is actually an array of arrays, because each row has
+ * a variable number of columns. So to actually build the cast linked list,
+ * we find the array of casts associated with the type, and loop through it
+ * adding the casts to the list. The one last trick we need to do is making
+ * sure the type pointer in the swig_cast_info struct is correct.
+ *
+ * First off, we lookup the cast->type name to see if it is already loaded.
+ * There are three cases to handle:
+ *  1) If the cast->type has already been loaded AND the type we are adding
+ *     casting info to has not been loaded (it is in this module), THEN we
+ *     replace the cast->type pointer with the type pointer that has already
+ *     been loaded.
+ *  2) If BOTH types (the one we are adding casting info to, and the
+ *     cast->type) are loaded, THEN the cast info has already been loaded by
+ *     the previous module so we just ignore it.
+ *  3) Finally, if cast->type has not already been loaded, then we add that
+ *     swig_cast_info to the linked list (because the cast->type) pointer will
+ *     be correct.
