## API
The module exports a new `Parser` instance, that can be used immediately. If you wish to create more parsers, you instead use the `Parser` constructor exported at `.Parser`:
```js
var Parser = require("simple-argparse").Parser;
var myParser = new myParser();
var myParser = new Parser();
```
While instantiating a parser, an output function may be registered with
the parser other than the default `console.log`
