C# Class Antlr4.Runtime.ParserInterpreter

A parser simulator that mimics what ANTLR's generated parser code does.
A parser simulator that mimics what ANTLR's generated parser code does. A ParserATNSimulator is used to make predictions via adaptivePredict but this class moves a pointer through the ATN to simulate parsing. ParserATNSimulator just makes us efficient rather than having to backtrack, for example. This properly creates parse trees even for left recursive rules. We rely on the left recursive rule invocation and special predicate transitions to make left recursive rules work. See TestParserInterpreter for examples.
