#initialize(working_folder: '.', terraform_variables: {}, terraform_init_arguments: {}) ⇒ Terraform

KSM: Maybe this should be a static class - pass in the working directory and the arguments, and call them. All the logic of assembling the command line arguments should be in the caller?? Since I want the caller to be able to spit out the things in a variables file, for instance.

#terraform_command_parameters(added_parameters = {}) ⇒ Object

KSM: Do we have this here, or do we munge all this up in the calling method and just pass in the processed list of arguments? For that matter, should we just call each of the actions on this class as static methods? Does this class really need to hold any kind of state?
