/**
  @deprecated
  @private

  In order to store defaults for a class, a prototype may need to create
  a default meta object, which will be inherited by any objects instantiated
  from the class's constructor.

  However, the properties of that meta object are only shallow-cloned,
  so if a property is a hash (like the event system's `listeners` hash),
  it will by default be shared across all instances of that class.

  This method allows extensions to deeply clone a series of nested hashes or
  other complex objects. For instance, the event system might pass
  `['listeners', 'foo:change', 'ember157']` to `prepareMetaPath`, which will
  walk down the keys provided.

  For each key, if the key does not exist, it is created. If it already
  exists and it was inherited from its constructor, the constructor's
  key is cloned.

  You can also pass false for `writable`, which will simply return
  undefined if `prepareMetaPath` discovers any part of the path that
  shared or undefined.

/**
  The purpose of the Ember Instrumentation module is
  to provide efficient, general-purpose instrumentation
  for Ember.

  Subscribe to a listener by using `Ember.subscribe`:

  ```javascript
  Ember.subscribe("render", {
    before: function(name, timestamp, payload) {

    },

    after: function(name, timestamp, payload) {

    }
  });
  ```

  If you return a value from the `before` callback, that same
  value will be passed as a fourth parameter to the `after`
  callback.

  Instrument a block of code by using `Ember.instrument`:

  ```javascript
  Ember.instrument("render.handlebars", payload, function() {
    // rendering logic
  }, binding);
  ```

  Event names passed to `Ember.instrument` are namespaced
  by periods, from more general to more specific. Subscribers
  can listen for events by whatever level of granularity they
  are interested in.

  In the above example, the event is `render.handlebars`,
  and the subscriber listened for all events beginning with
  `render`. It would receive callbacks for events named
  `render`, `render.handlebars`, `render.container`, or
  even `render.handlebars.layout`.
