* Chapter 3 - add vars and lexical scope.
* Fix typo
* Overhaul graph viz
Makes the scopes pointing into the graph being build more visually appealing.
Constants are a printed with just the constant value.
* Fix control edge color
* Fix missing grouping operator parse
Add a parens test.
Shorten names 'Identifier' to 'Id'
_lexer.match -> match
require() passes a Node thru, so can be flow-coded.
Uniform syntax error messages.
Handy Lexer.toString for debugging.
Drop Optional for null returns; less total code; less objects; less confusion.
camelCase some fcns.
* All parser helpers return Node, not void.
Drop _ret. parseBlock and parseStatement now the same.
* CLosely align chap2 and chap3 parsers
Mostly whitespace aligned; dragged a few functions around to make more sense.
I think the diff from Ch2 and Ch3 is down a few differences about what is a statement, plus all the symbol stuff for scopes and variables.
* Add examples illustrating the symbol table creation.
* Update docs and comments
