additional features:
* short and long options are tied together
* options have help strings, so fancy_getopt could potentially
create a complete usage summary
* options set attributes of a passed-in object

handy extra functionality:
* short and long options are tied together
* options have help strings, and help text can be assembled
from them
* options set attributes of a passed-in object
* boolean options can have "negative aliases" -- eg. if
--quiet is the "negative alias" of --verbose, then "--quiet"
on the command line sets 'verbose' to false
