/* -----------------------------------------------------------------------------
* 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 staticly 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.
