Deal with the 'No Output nodes found' error

Remember that Brainscript is case sensitive. So code like

# Special Nodes
OutputNodes = (ol)

will not work as expected. The names of all special nodes are lower camelCase

# Special Nodes
featureNodes = (features)
labelNodes = (labels)
criterionNodes = (ce)
evaluationNodes = (errs)
outputNodes = (ol)
