[TCML] winding direction

[Frank]

Unless you are making a twin Tesla system, the winding direction is 
not relevant for the primary and secondary.

Even an iron core does not care in the case of a single primary and secondary.
If you have a tapped winding then you have to pay attention to the 
direction of the windings for sure.
I have used iron core transformers to add or subtract voltages by 
reversing windings for certain applications.
