Feature request: direct access to source fields

[xapple]

When looking at a GenBank entry there often is interesting information in the "source" feature, which actually contains several subfields. From instance below one can see the "host" information:

I end up having to wrap the gb_io.Record class with another class to access this information. Also I end up constantly having to replace newlines with spaces.

class GenBankRecord:

    def __init__(self, rec):
        """Get a record instance from gb_io"""
        self.rec = rec

    @functools.cached_property
    def source(self):
        """Parse the first feature which is always 'source'"""
        return next(iter(self.rec.features))

    @functools.cached_property
    def fields(self):
        """Get all subfields of source."""
        return self.source.qualifiers.to_dict()

    @functools.cached_property
    def host(self):
        if 'host' in self.fields:
            return self.fields['host'][0].replace('\n', ' ')
        return ''

It would be nice to just do rec.host no?

Regarding field access, the python bindings are a separate project, please open an issue there.

The issue with the newlines belongs here though, it's a bit of a tricky one however, see this issue for some more discussion.

OK I'll post the issue there and close this one. Thanks.
