# = SuperStruct
#
# SuperStruct is an enhanced version of the Ruby Standar library <tt>Struct</tt>.
#
# Compared with the original version, it provides the following additional features:
# * ability to initialize an instance from Hash
# * ability to pass a block on creation  
#
class SuperStruct < Struct

  # Overwrites the standard Struct initializer
  # to add the ability to create an instance from a Hash of parameters.
  #
  #   attributes = { :foo => 1, :bar => "baz" }
  #   Struct.new(attributes)
  #   # => #<Struct foo=1, bar="baz">
  #
  # If block is given, the block is called on self.
  #
  def initialize(*args, &block)
    if args.first.is_a? Hash
      initialize_with_hash(args.first)
    else
      super
    end
    yield(self) if block_given?
  end
