* Default is now previous single-verbosity level; it was too annoying to
add the -v every time.
** -q/--quiet has been added to return to the previous default output
ADDED:
* num-addrs subcommand, to get the number of hosts/addresses in a given
prefix length
* get-net subcommand, to more easily get a single subnet from either the
beginning or the end of a prefix. (MUCH FASTER than CIDR-splitting!)
