When training transforms involving pipes, and projecting from one
stage to the next, break the training data into single item
templatelists (similarly to what is typically done by Distribute
transforms durign training). This allows e.g. ExpandTransform to work
as expected.

If 'subject' is set, but 'label' is not set, before remapping subject
to an integer, check if it is already a number. In this case, no
remapping is necesasry, and in fact remapping caused problems when
evaluating regression output
