Implement the {#generate_output} method required by
 the {Filter} API. Compiles each input file with Uglify.

 @param [Array<FileWrapper>] inputs an Array of
   {FileWrapper} objects representing the inputs to
   this filter.
 @param [FileWrapper] output a single {FileWrapper}
   object representing the output.
