A macaroon bakery implementation.

The bakery implements the protocol used to acquire and discharge macaroons
over HTTP.

#### new Bakery(config)

Initialize a macaroon bakery with the given parameters.

| Param | Type | Description |
| ------------------------------ | --------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| config | Object | optional config. |
| config.onSuccess | function | a function to be called when the request completes properly. |
| config.protocolVersion | number | the macaroon protocol version that the bakery should use. |
| config.storage | function | the storage used to persist macaroons. It must implement the following interface: |
| config.storage.get | function | get(key) -> value. |
| config.storage.set | function | set(key, value, callback): the callback is called without arguments when the set operation has been performed. If not provided, it defaults to BakeryStorage using an in memory store. |
| config.visitPage | function | the function used to visit the identity provider page when required, defaulting to opening a pop up window. It receives an error object. |
| config.visitPage.Info | Object | an object containing relevant info for the visit handling. |
| config.visitPage.Info.WaitUrl | String | the url to wait on for IdM discharge. |
| config.visitPage.Info.VisitUrl | String | the url to visit to authenticate with the IdM. |
| config.visitPage.jujugui | function | an optional value specifying a method to use against idm to authenticate. Used in non interactive authentication scenarios. |
| config.sendRequest | function | a function used to make XHR HTTP requests, with the following signature: func(path, method, headers, body, withCredentials, callback) -> xhr. By default an internal function is used. This is mostly for testing. |
