In case searchFor exists in listToBeSearched, web::match returns result, otherwise an empty string.
web::match treats v1 as a list. Thus, web::match "ok" {tv dvd vcr} dvd will return ok.
Options are -path path, -prefix prefix, and -remove. Returns a unique name of a temporary file. The maximum of guaranteed unique names per application is system dependent. This command just returns the name of a file. It is the programmers job to handle the file, for example to open it. Note that Websh keeps an internal list of all file names generated with web::tempfile and will attempt to delete all files when the interpreter dies.
