How to use JSONParse.js

I can't seem to get JSONParse to work in any fashion.

this code:

import JSONParse;

function Start(){
    var j = new JSONParse("{a:'string'}");  
}

produces the error:

NullReferenceException: Object reference not set to an instance of an object

JSONParse.JSONParse

JSONParse: http://www.unifycommunity.com/wiki/index.php?title=JSONParse

any help?

@R-GiGgS84, for the error of support slicing, have a look at following links,
