Implementation of JSON Patch and JSON Pointer RFC.

Implements specs of the JSON Patch and JSON pointer RFCs:

This works against Ruby objects, so you should load the JSON to Ruby, process it, then emit as JSON again.

patch = Hana::Patch.new [
  { 'op' => 'add', 'path' => '/baz', 'value' => 'qux' }
]

patch.apply('foo' => 'bar') # => {'baz' => 'qux', 'foo' => 'bar'}
