one hot encode a little optimization

[bai0335]

in one hot encode , there is no need count and filte when the threshold less than 1.

code is :
DataSet<Tuple3<Integer, String, Long>> countTokens = StringIndexerUtil.countTokens(inputRows, true)
.filter(new FilterFunction<Tuple3<Integer, String, Long>>() {
@OverRide
public boolean filter(Tuple3<Integer, String, Long> value) {
return value.f2 >= thresholdArray[value.f0];
}
});

Thanks, we'll optimize it later.
