MethodAccessWithOverride does not apply to existing hash

[jeremy-hubble]

MethodAccessWithOverride only overrides default methods when the item is manually set. I would like to be able to have methods available when creating from an existing hash.

class MyOverridingHash < Hash
  include Hashie::Extensions::MethodAccessWithOverride
end

hash = {}
hash['key'] = 'foo';
hash['val'] = 'bar';
overriding = MyOverridingHash.new(hash)
overriding.key   # produces error. Expect 'foo'
overriding.key = 'foo'
overriding.key  # 'foo'

It's possible that we want to change behavior of MethodAccessWithOverride to do this, or have another MethodAccessWithOverrideInitializer or similar. I would explore both routes.
