Convert any string (even reserved words) to a valid javascript identifier.

Useful when writing compile to JS languages.

```js

var toId = require('to-js-identifier');

//valid ids just go right through

toId('foo') === 'foo'

//convert your string to a valid js identifier

toId('not-js') === 'not$45$js'

//as use can see it wraps invalid chars with '$' + c.charCodeAt(0) + '$'

//Even though $ is a valid identifier, this function will escape it, so it

//is not possible that 2 inputs generate the same output

toId('$') === '$36$'

//reserved words are escaped

toId('null') === '$null$'

toId('var')  === '$var$'

// yes I know undefined is technically an identifier, but it shouldn't be!!!

toId('undefined') === '$undefined$'

```
