	// StaticHandler returns a new Handler which is ready

	// Note:
	// The only difference from package-level `StaticHandler`
	// is that this `StaticHandler` receives a request path which
	// is appended to the party's relative path and stripped here.

	// Usage:
	// app := iris.New()
	// ...
	// mySubdomainFsServer := app.Party("mysubdomain.")
	// h := mySubdomainFsServer.StaticHandler("./static_files", false, false)

	// accepts only one required parameter which is the systemPath,

	// If second parameter is empty, otherwise the requestPath is the second parameter
	// it uses gzip compression (compression on each request, no file cache).
	//
	// Returns the GET *Route.

	// StaticEmbedded  used when files are distributed inside the app executable, using go-bindata mostly
	// First parameter is the request path, the path which the files in the vdir will be served to, for example "/static"
	// Second parameter is the (virtual) directory path, for example "./assets"
	// Third parameter is the Asset function
	// Forth parameter is the AssetNames function.
	//
	// Returns the GET *Route.

	// Example: https://github.com/kataras/iris/tree/master/_examples/file-server/embedding-files-into-app

	// Favicon serves static favicon
	// accepts 2 parameters, second is optional
	// favPath (string), declare the system directory path of the __.ico
	// requestPath (string), it's the route's path, by default this is the "/favicon.ico" because some browsers tries to get this by default first,
	// you can declare your own path if you have more than one favicon (desktop, mobile and so on)
	//
	// this func will add a route for you which will static serve the /yuorpath/yourfile.ico to the /yourfile.ico
	// (nothing special that you can't handle by yourself).
	// Note that you have to call it on every favicon you have to serve automatically (desktop, mobile and so on).

	// StaticWeb returns a handler that serves HTTP requests

	// second parameter: the system directory
	//
	// for more options look router.StaticHandler.
	//
	//     router.StaticWeb("/static", "./static")
	//
	// As a special case, the returned file server redirects any request
	// ending in "/index.html" to the same path, without the final
	// "index.html".
	//
	// StaticWeb calls the StaticHandler(systemPath, listingDirectories: false, gzip: false ).
	//
	// Returns the GET *Route.

	// Layout oerrides the parent template layout with a more specific layout for this Party
