Request - simple lisp parsing example

[bddap]

This would be helpful.

sorry, I do not have the time to work on this, but if you find or write a good one, I could add it to the list of examples

@bddap didn't see this before posting #903 (comment) ; I made an s-expression parser using nom5 which is MIT licensed.

I'd be willing and able to contribute to a lisp parser example. What exactly did you have in mind? Something like S-expressions or a full parser for scheme or something?

[bddap]

Awesome! A very simple s-expression parser, something less than 100 lines, would make it easy to get started using nom. The json example is a good start, but an s-expr parser could be much simpler.

@bddap
I just hacked out a little lisp https://github.com/MarkMcCaskey/nom/blob/master/examples/s_expression.rs ; I'm going to sleep now, but I'll add comments, clean it up, and make a PR tomorrow.
