Provide option metadata

[con-f-use]

For the following option definition

-c --count=<int>    Option for a count of some kind [default: 42] 

Is there a way to retrieve the default value ( 42) and the value of the value designation (<int>) programatically? I.e. is the a way to get from the resulting args after docopt-ng is done parsing? I have an oustanding PR in original docopt for that sort of change but, as well all know, that's not going to be merged.

To answer my own question: The PR I just made will take care of the <int> thing, while the 42 thing (and, once the PR is merged, the argument type, i.e. <int>) can be accessed via the parse_defaults function:

from docopt import docopt, parse_defaults
args = docopt(__doc__)
atypes = {(o.longer or o.short):o.atype, o.value for o in parse_defaults(__doc__)}
defaults = {(o.longer or o.short):o.value, o.value for o in parse_defaults(__doc__)}

I'm going to close this as not going to implement, see #4 for discussion.
