-#### Multi values
-
-Slice flags(Float64SliceFlag, Int64SliceFlag, IntSliceFlag, StringSliceFlag) are designed to accept multi values.
-
-Here is a sample of setting multi values for slice flags:

-	"output": "0-float64Sclice cli.Float64Slice{slice:[]float64{13.3, 14.4, 15.5, 16.6}, hasBeenSet:true}\n1-int64Sclice cli.Int64Slice{slice:[]int64{13, 14, 15, 16}, hasBeenSet:true}\n2-intSclice cli.IntSlice{slice:[]int{13, 14, 15, 16}, hasBeenSet:true}\n3-stringSclice cli.StringSlice{slice:[]string{"parsed1", "parsed2", "parsed3", "parsed4"}, hasBeenSet:true}",

 You can make a flag required by setting the `Required` field to `true`. If a user
