object JsonMapper

This object has methods that use a collection of codecs for converting between Json and user defined case classes. For case classes, Shapeless is used. Here is an example:

import com.persist.JsonOps._
import com.persist.JsonMapper._
import com.persist.json._   // brings in implicit codecs!

case class Person(name:String, age:Option[Int])
case class Group(city: String, people:Seq[Person], var cnt:Int, props:JsonObject)

val j:Json = Json("""{city:"Seattle", cnt:2, props:{i:1, j:2},
                      people:[{name:"Joe"},
                              {name:"Tom", age:20}]
                     }""")

val group:Group = ToObject[Group](j)

val j1:Json = ToJson(group)

assert(j1 == j)
