ANTLR4 what does ATN stand for?

Question

I'm surprised this is not explained anywhere on the ANTLR website nor in any of the documentation, but what does ATN (not ANT) stand for? Knowing what the acronym stands for would help me understand the role of the ATN, ATNSimulator, etc. components of the library. Can anyone clear this up for me?
