Add Pi approximation Java example
Hadoop and Spark have a Pi approximation basic example (similarly to
WordCount, PageRank ...), so for homogeneity it is worth having it in Flink as
well.
Note:
The final result, count, which in this case is the approximation of Pi had
to be assigned the type DataSet<Double> instead of just Double (due to Flink
limitation)
So aside from executing a summation, the reduce (at the collector level)
also does a little math operation, which could have not been applied on type
DataSet.
