Detailed Description
       A node representing batch normalization for inference or training  Batch normalization operates differently for inference and training. For
       inference, the normalization is done according to a static statistical representation of data saved during training. For training, this
       representation is ever evolving. In the low level MPS batch normalization interface, during training, the batch normalization is broken up
       into two steps: calculation of the statistical representation of input data, followed by normalization once the statistics are known for
       the entire batch. These are MPSCNNBatchNormalizationStatistics and MPSCNNBatchNormalization, respectively.

       When this node appears in a graph and is not required to produce a MPSCNNBatchNormalizationState -- that is,
       MPSCNNBatchNormalizationNode.resultState is not used within the graph -- then it operates in inference mode and new batch-only statistics
       are not calculated. When this state node is consumed, then the node is assumed to be in training mode and new statistics will be calculated
       and written to the MPSCNNBatchNormalizationState and passed along to the MPSCNNBatchNormalizationGradient and
       MPSCNNBatchNormalizationStatisticsGradient as necessary. This should allow you to construct an identical sequence of nodes for inference
       and training and expect the to right thing happen.
