> 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.
