val file : file React.eventfile occurs whenever a file is dropped on the application.
An occurence corresponds either to a file or to a directory.
Multiple files or directories can be dropped together and each
of those will result in one occurence on Useri.Drop.file (which means
that you cannot detect that a set of files where dropped
together).
