Use as library

[zhelyan]

Description

Basically delays the template compilation so we can load code from external files before the dsl is evaluated. My use case is using this gem as a library where one dsl template can be customized by injecting various constructs, for instance:

• org wide parameters / outputs (project, environment etc.)
• params object used to access parameters defined in yml file
• resource abstractions where 2 or more resources are defined in a component file and can be loaded in any template; think elb + asg group

Steps to Test or Reproduce

bundle exec rspec

Environment

ruby 2.3.4

btw Travis tests fail because template validation needs AWS credentials which should be addressed in separate PR
