*
* Sample usage for localdata.js
*
* Store - $.localdata("name", "value");
* value can be integer, string, object, array
* $.localdata("name", [1,2,3,4,5]);
* $.localdata("name", {name: "John Dow", email: "john@company.com"});
*
* Read - $.localdata("name");
* Delete One Item By Key - $.localdata.remove("name"); or $.localdata("name",null,{expires:-1});
* Delete entire cookie - $.localdata.clear();
* Count Stored Items - $.localdata.count();
* Force Reload - $.localdata.reload();
* Get/Set cookie configuration - $.localdata.config() and $.localdata.config({expires: 'in days', path: 'your new path', domain: 'domain', 'secure': true or false}) defaults are expires: 365, path: '/', domain: '', 'secure': ''
* Get/Set cookie prefix - $.localdata.prefix() and $.localdata.prefix("new_prefix_") default is "localdata_cookie_"
*
