Build stacks by including other ruby files

[johnf]

I've created a naive implementation in #151 which would allow the following

You have a master file env_stack.rb

CloudFormation {
  Description "Test"
  include 'parameters_one'
  include 'parameters_two'
}

you can then create _parameters_one.rb and _parameters_two.rb

Parameter("One") {
  String
}

Parameter("Two") {
  String
}

This will generate the same output as

CloudFormation {
  Description "Test"
  Parameter("One") {
    String
  }
  Parameter("Two") {
    String
  }
}

Does this make sense?

@johnf really like this idea, interesting how you're able to define a method called include - I thought it was a reserved keyword.

I'll take a look at the PR, I'd done something similar in a previous project but by including the different templates into one big eval, this makes a lot more sense. Nice work!

[johnf]

include probably is technically reserved but probably only inside a module so that might be why it works here. Actually according to http://docs.ruby-lang.org/en/2.2.0/keywords_rdoc.html maybe it isn't reserved?

I was going to go with Include originally but didn't want to risk AWS using it for something.

Maybe _Include ?

I'll continue the conversation in: #151
