NAME
       <MPSCNNConvolutionDataSource>

SYNOPSIS
       #include <MPSCNNConvolution.h>

Detailed Description
       Provides convolution filter weights and bias terms  The MPSCNNConvolutionDataSource protocol declares the methods that an instance of
       MPSCNNConvolution uses to obtain the weights and bias terms for the CNN convolution filter.

       Why? CNN weights can be large. If multiple copies of all the weights for all the convolutions are available unpacked in memory at the same
       time, some devices can run out of memory. The MPSCNNConvolutionDataSource is used to encapsulate a reference to the weights such as a file
       path, so that unpacking can be deferred until needed, then purged soon thereafter so that not all of the data must be in memory at the same
       time. MPS does not provide a class that conforms to this protocol. It is up to the developer to craft his own to encapsulate his data.

       Batch normalization and the neuron activation function are handled using the -descriptor method.

       Thread safety: The MPSCNNConvolutionDataSource object can be called by threads that are not the main thread. If you will be creating
       multiple MPSNNGraph objects concurrently in multiple threads and these share MPSCNNConvolutionDataSources, then the data source objects may
       be called reentrantly.
