Change Features class to no longer inherit from UserDict. Fix unbound local bug in Features.
0.2.22
Improved dealing with features that have multiple genome ranges to fix https://github.com/VirologyCharite/gb2seq/issues/11
0.2.21
Added `--translated` option to `bin/describe-genome.py`. This will extract all the features that are translated.
0.2.20
'function' may not be present on stem_loop features. Added `--slashReplacement` and `--spaceReplacement` to `bin/describe-genome.py` for more control over creating output filenames.
0.2.19
More robust treatment of feature names. After processing everything we want to treat specially, just look for things that have a "product" and ignore those that don't.
0.2.18
Added `ncRNA` to known feature types. Probably I should just ignore all unknown feature types but at this point I still want to see them.
