+ * Copyright (c) 2016 Adriano Tinoco d'Oliveira Rezende
+ *
+ * Based on the JSON parser by Patrick van Bergen
+ * http://techblog.procurios.nl/k/news/view/14605/14863/how-do-i-write-my-own-parser-(for-json).html
+ *
+ * Changes made:
+ *
+ * - Optimized parser speed (deserialize roughly near 3x faster than original)
+ * - Added support to handle lexer/parser error messages with line numbers
+ * - Added more fine grained control over type conversions during the parsing
+ * - Refactory API (Separate Lexer code from Parser code and the Encoder from Decoder)
