Fix error reporting for mean IOU
 
There are two types of problems with reporting mean IOU error
1) Final error in CNTK is calculated as average of mini-batch errors.
Since mean IOU is calculated by accumulating intersection and union,
result for the last mini batch should be used instead of average.
2) Reported error is averged with number of processed samples (minibatch
size) which causes problems when working with minibatch size bigger than
1. In that case, reported error will be smaller <minibatch_size> times.
Adding logic that decides whether evaluation nodes accumulated error based
on network topology.
In case of distributed calculation, average of aggregate errors calculated
on different nodes will be reported.
Refactor criteria accumulation. Criteria now knows if evaluation node
is accumulating error or not.
