A Concrete Syntax Tree Node.
This structure represents the whole parse tree of the grammar
This means that information on each and every Token is present.
This is unlike an AST (Abstract Syntax Tree) where some of the syntactic information is missing.
For example given an ECMAScript grammar, an AST would normally not contain information on the location
of Commas, Semi colons, redundant parenthesis ect, however a CST would have that information.
