/**
* mw.Upload.BookletLayout encapsulates the process of uploading a file
* to MediaWiki using the {@link mw.Upload upload model}.
* The booklet emits events that can be used to get the stashed
* upload and the final file. It can be extended to accept
* additional fields from the user for specific scenarios like
* for Commons, or campaigns.
*
* ## Structure
*
* The {@link OO.ui.BookletLayout booklet layout} has three steps:
*
* - **Upload**: Has a {@link OO.ui.SelectFileWidget field} to get the file object.
*
* - **Information**: Has a {@link OO.ui.FormLayout form} to collect metadata. This can be
* extended.
*
* - **Insert**: Has details on how to use the file that was uploaded.
*
* Each step has a form associated with it defined in
* {@link #renderUploadForm renderUploadForm},
* {@link #renderInfoForm renderInfoForm}, and
* {@link #renderInsertForm renderInfoForm}. The
* {@link #getFile getFile},
* {@link #getFilename getFilename}, and
* {@link #getText getText} methods are used to get
* the information filled in these forms, required to call
* {@link mw.Upload mw.Upload}.
*
* ## Usage
*
* See the {@link mw.Upload.Dialog upload dialog}.
*
* The {@link #event-fileUploaded fileUploaded},
* and {@link #event-fileSaved fileSaved} events can
* be used to get details of the upload.
*
* ## Extending
*
* To extend using {@link mw.Upload mw.Upload}, override
* {@link #renderInfoForm renderInfoForm} to render
* the form required for the specific use-case. Update the
* {@link #getFilename getFilename}, and
* {@link #getText getText} methods to return data
* from your newly created form. If you added new fields you'll also have
* to update the {@link #clear} method.
*
* If you plan to use a different upload model, apart from what is mentioned
* above, you'll also have to override the
* {@link #createUpload createUpload} method to
* return the new model. The {@link #saveFile saveFile}, and
* the {@link #uploadFile uploadFile} methods need to be
* overridden to use the new model and data returned from the forms.
*
* @class
* @extends OO.ui.BookletLayout
*
* @constructor
* @param {Object} config Configuration options
* @cfg {jQuery} [$overlay] Overlay to use for widgets in the booklet
* @cfg {string} [filekey] Sets the stashed file to finish uploading. Overrides most of the file selection process, and fetches a thumbnail from the server.
