Major Description
The aim of jira is to introduce a non-trivial IMRU example that does Pipelined BroadcastReduce in K iterations.
Update function returns an integer array containing value k+1 in iteration k and gets as input the sum of arrays from all mappers.
Map function returns the same array it gets as input from update function.
Update function verifies that it gets as input (k+1)*no. of mappers and map function verifies that it gets as input k+1 in iteration k.
