MethodAccess should inject itself into subhashes

[dblock]

Just like Hashie::Extensions::IndifferentAccess.

class MyHash < Hash
  include Hashie::Extensions::MergeInitializer
  include Hashie::Extensions::IndifferentAccess
  include Hashie::Extensions::MethodAccess

end

h = MyHash.new(foo: { bar: 1 })

2.0.0-p598 :010 > h[:foo]
 => {"bar"=>1} 
2.0.0-p598 :011 > h['foo']
 => {"bar"=>1} 
2.0.0-p598 :009 > h.foo
 => {"bar"=>1} 

2.0.0-p598 :013 > h[:foo][:bar]
 => 1 
2.0.0-p598 :014 > h['foo']['bar']
 => 1 
2.0.0-p598 :015 > h.foo.bar
NoMethodError: undefined method `bar' for {"bar"=>1}:Hash
    from (irb):15
    from /Users/dblock/.rvm/rubies/ruby-2.0.0-p598/bin/irb:12:in `<main>'

vs. Mash

2.0.0-p598 :017 > h = Hashie::Mash.new(foo: { bar: 1 })
 => #<Hashie::Mash foo=#<Hashie::Mash bar=1>>

I don't think it should.

Comparing to Mash your custom class lacks mash-like deep initializer which is a different concern from MethodAccess. So you just need a smart initializer extracted from Mash (just like MergeInitializer but deep), probably implemented as a separate extension.
So It's a initializer issue, not an issue of MethodAccess.

Fair enough @marshall-lee!
