/**
* @page neo_browser File/Mailbox Browser Dialog
*
* The File/Mailbox Browser Dialog lets the user select from a list of files or
* mailboxes.
*
* This is a @ref gui_simple
*
* ## Windows
*
* | Name | Type | See Also |
* | :------------- | :------------- | :------------------------ |
* | Browser Dialog | WT_DLG_BROWSER | mutt_buffer_select_file() |
*
* **Parent**
* - @ref gui_dialog
*
* **Children**
* - See: @ref gui_simple
*
* ## Data
* - #Menu
* - #Menu::mdata
* - #BrowserState
*
* The @ref gui_simple holds a Menu. The Browser Dialog stores its data
* (#BrowserState) in Menu::mdata.
*
* ## Events
*
* Once constructed, it is controlled by the following events:
*
* | Event Type | Handler |
* | :-------------------- | :-------------------------- |
* | #NT_CONFIG | browser_config_observer() |
* | #NT_WINDOW | browser_window_observer() |
*
* The Browser Dialog doesn't have any specific colours, so it doesn't need to
* support #NT_COLOR.
*
* The Browser Dialog does not implement MuttWindow::recalc() or MuttWindow::repaint().
*
* Some other events are handled by the @ref gui_simple.
