function t=processtargets(net,t)
%PROCESSTARGETS Applies a network's preprocessing settings to target values
%
% Syntax
%   
%   t2 = processtargets(net,t1)
%
% Description
%
%   PROCESSTARGETS(net,t1) takes a network and target values (either a
%   matrix or a cell array of matrices) and returns those values after
%   applying the network's preprocessing settings.
%
%   If T is a cell array, it may have as many rows as network targets,
%   or as many rows as network layers.
