Introducing ELR(Expectational LR) Parser

• The ELR parser will actively use the Lexer to lex the input string to tokens according to the grammar rules.
• Re-Lex: If the lexed token can't be accepted, the ELR parser will try to restore & re-lex input.

Lexer

• Add Lexer.trimStart/clone/dryClone/take.
