What is json-filter?
json-filter extends JSON with a filter function that will helps validate 'unverified' JSON objects.
- Verifies object name and value type
- Allows for multiple types of objects (arrays, json objects, strings, numbers etc..)
- Verifies array objects with a single filter
- Able to verify complex json objects (nested arrays, objects etc..)
- Allows for simple switch cabilitity (case & default)

JSON.filter = require('node-json-filter');
var filter = new JSON.filter( {

"num":"$number",
"bool":"$boolean",
"obj":{"str":"$string"},
"arry":["$string"],
"arryobj":[
{"str":"$string"}

"complex":{
"arry":[
{"num":"$number"}

"num":"$number"
},
"parsing":[{
