iterating iso metadata? about isoparser

[dougstarfish]

I'll could use vars(iso.volume_descriptors['primary']) but a 'header()' method to pull all of them in one swoop would be pretty useful as a generalized mechanism. What do you think?

something like

class PrimaryVD ...
...
def header(self):
return self.dict.items()

and you could call it like

for k, v in iso.volume_descriptors['primary'].header():
print(k + ' = ' + str(v))

This is a deliberate decision as the underlying data is a kind of struct rather than a mapping. Elsewhere in the library we use object attributes for storing data that's specific to that class of object. To me, a dict is the wrong abstraction for VD entries given its set of keys is pre-defined. For your use case I think vars() should do the trick. Hope this sounds reasonable!
