/// A gram matrix layer
///
/// The MLComputeGramMatrix specifies a layer which computes the uncentered cross-correlation
/// values between the spatial planes of each feature channel of a tensor. If the input tensor batch is
/// x = x[b, y, x, c], where 'b' is batch index, 'y' and 'x' are the spatial coordinates and 'c' is the feature channel
/// index then this layer computes the values:
///
/// y = y[b, 1, f, c] = alpha * sum_{x,y} x[b,y,x,f] * x[b,y,x,c], where 'alpha' is a scaling factor.
///
/// This operation can be interpreted to be computing all combinations of fully connected layers
/// between the different spatial planes of the input tensor. The results are stored in the feature channel and
/// 'x'-coordinate indices of the output batch.
///
/// The operation is performed independently for each tensor in a batch.
///
