# The MergeInitializer is a super-simple mixin that allows
# you to initialize a subclass of Hash with another Hash
# to give you faster startup time for Hash subclasses. Note
# that you can still provide a default value as a second
# argument to the initializer.
#
# @example
# class MyHash < Hash
# include Hashie::Extensions::MergeInitializer
# end
#
# h = MyHash.new(:abc => 'def')
# h[:abc] # => 'def'
#
