class Rley::ParseRep::CSTBuilder

The purpose of a CSTBuilder is to build piece by piece a CST (Concrete Syntax Tree) from a sequence of input tokens and visit events produced by walking over a GFGParsing object. Uses the Builder GoF pattern. The Builder pattern creates a complex object (say, a parse tree) from simpler objects (terminal and non-terminal nodes) and using a step by step approach.
