/*
 * token.cpp
 * This file implements the Token class defined in token.h.
 * The Token class represents a lexical token in the source code.
 * Each Token has a type, a lexeme, a literal value, and the line number where it was found in the source code.
 * The Token class includes a method for converting a Token to a string for debugging purposes.
