  ##
  # A collection of DSL extensions for use with various worlds to allow the use of some simpler
  # dsl language in them.
  #
  # For rspec, in spec helper add config.extend RestDSL::DSLExtensions::<<extension>>
  # In cucumber World(RestDSL::DSLExtensions::<<extension>>)
  # Each extension can also be extended onto a class like normal to use it in that class
  module DSLExtensions

    ##
    # Adds a DSL method for parsing information from a file, parser list can be overridden by redefining file_parsers
