New issue 420: Make metadata into an OrderedDict
https://bitbucket.org/blais/beancount/issues/420/make-metadata-into-an-ordereddict
Martin Michlmayr:
I’m wondering whether it would be possible to make metadata \(both on transactions and postings\) into an OrderedDict.
I have written an importer which basically does something like:
```
meta = data.new_metadata(
f.name, index)
meta['donor_name'] = get_name(row)
meta['donor_email'] = row['Email']
```
It makes sense to have name first, email second, but currently beancounts sorts the keys and email comes out first.
Can you think of any disadvantage of using an OrderedDict? If not, maybe I can try to see if I can contribute a patch.
