Feature: Parameters with default value

[denisdefreyne]

Idea: allow parameters to be defined with a default value. For example:

param :host
param :port, transform: method(:Integer), default: 3000

For simplicity, allow parameters with a default value to only appear at the end. The following would therefore not be possible:

param :foo, default: 'xxx'
param :bar

param :foo
param :bar, default: 'xxx'
param :qux
param :abc, default: 'yyy'

I image that this restriction will be fine, because the CLI will become complicated to use otherwise anyway.

Guys, has this feature been released?...
I'm getting an error on set default:

/.../ruby-2.5.1/lib/.../cri-2.15.0/lib/cri/command_dsl.rb:173:in 
    `param': unknown keyword: default (ArgumentError)

UPD...
Yeah, I guess not, here are no commits yet.
It would be great to have this feature. It will allow to make a parameter make as an optional one by setting empty value like nil or ''.

@andkirby It’s not implemented yet! This GitHub issue serves as a to-do item.
