> We should add a new {{threshold}} utility function that accepts a matrix
> {{X}} and a threshold parameter {{thresh}} and returns an indicator matrix
> {{out}} with values in {{{0, 1}}} depending on whether or not the values in
> {{X}} are above {{thresh}}. We could use this, for example, for determining
> the predicted class in a binary classification problem given the output of a
> sigmoid layer.
