Please add complete example into ReadMe

[harrison314]

Hello,
I tried to start using parakeet because its API looks good and is practically used.

Well, at the very beginning I ran into the problem of which nuggets to install in order for the example given on CodeProject to work. I solved that.

I had a problem with practical use, I corrected the grammar, but the ReadMe lacks how to parse the input, how to pass AST or tokens,...

Could you add a complete example to the ReadMe, for example a simple calculator? It would be enough to show the grammar, show its notation in Parakeet, how to parse the input, display the AST/tokens on the console, calculate the result of the math formula (eg. 32 + 14 * (2 + 3) - 1).

I mean the grammar for the calculator, which is often used in examples for parsers:

E ::= E '+' T | E '-' T | T
T ::= T '*' F | T '/' F | F
F ::= number | '(' E ')'
number ::= `[1-9]\d*`

you might want to take a look at Parakeet.Grammars for some examples.
there are easy examples like the CsvGrammar and SExpressGrammar, or some more advanced examples such as CSharpGrammar or JsonGrammar.

basically you want to extends BaseCommonGrammar, and define your language by defining rules.
