We need a way of flagging a default command #77

The question is whether it's possible to specify it so it can only be done once.

Yeah, I think so!

But maybe not on Document — since a multi-cli might have several default subcommands in various paths. For example,

• git remote -> git remote show
• git stash -> git stash save

What if Command (including the root command) has a field defaultCommand that's a string instead of an array?

You'd express the git example like this:

{
 "name": "git", // pseudo: depends on where we land with #70 
 "commands": [
 {
 "name": "remote",
 "defaultCommand": "show",
 "commands:": [
 {
 "name": "show",
 // ...
 }
 ]
 },
 {
 "name": "stash",
 "defaultCommand": "save",
 "commands:": [
 {
 "name": "save",
 // ...
 }
 ]
 },
 // ...
 ]
}

@patriksvensson, is my answer acceptable to you? If so, I'd love to land this change.
