Python API alpha

I've fixed some of the issues I was having with Python. A simple example:

[mcmaster@gespenst bin]$ ipython

In [1]: import uvudec

In [2]: uvd = uvudec.uvd.getUVDFromFileName('candela.bin')

In [3]: dissassembly = uvd.disassemble()

In [4]: print dissassembly[0:200]
LJMP #0x0026
MOV R7, A
MOV R7, A
MOV R7, A
MOV R7, A
MOV R7, A
MOV R7, A
MOV R7, A
MOV R7, A
LJMP #0x0DA9
MOV R7, A
MOV R7, A
MOV R7, A
MOV R7, A
MOV R7, A
MOV R7, A
MOV R7, A
MOV R7, A
MOV R7, A
MOV

Basically, this is the sort of construct I needed:

%typemap(in, numinputs=0) UVD ** (UVD *temp)
{
$1 = &temp;
}

%typemap(argout) (UVD **)
{
PyObject *to_add = SWIG_NewPointerObj(*$1, $descriptor(UVD *), SWIG_POINTER_OWN);
$result = SWIG_AppendOutput($result, to_add);
}

I initially had some issues with appending objects to the none type generated in the default exception handler (I actually need to look more into why this was required in the first place), but they seem to have gone away now. The issue was that if you appended an object to a none type, it would return a list with the object being the only member of that list...w/e.
Things seem to work now at least at a basic level, but there's a bunch of things in both C++ and Python/SWIG that will need to be cleaned up for this to be convenient to use. I guess the next big thing will be to figure out how to make my iterators translate cleanly. In particular, it doesn't look like they are being compared correctly. Maybe need to add some sort of generator translation functionality as well?
Example of current iterator code:

itr = uvd.begin()
while itr is not uvd.end() and itr.getPosition() < 0x10:
print '0x%04X: %s' % (itr.getPosition(), itr.getCurrent())
itr.next()
