Where are the local and global hints networks defined?

I cannot find a reference to either the local or global hints networks anywhere in the source code. I've had a look at the definition of the SIGGRAPHGenerator class, but that seems to be just the main colorization network. I would be very grateful for pointing me to the relevant lines. Thank you.
