Detailed Description

A static utility class that performs lexical analysis on a config string.

The Lexer breaks down a raw string into a sequence of Tokens, which can then be consumed by the Parser. It handles basic elements like keywords, strings, numbers, and punctuation, ignoring whitespace and comments.
