Some unit test code to compare coconut against Argo and By_Hand decoding.

Coconut_Test.swift

    func test_measure_coconut() {
        let json = THGCodable.JSON(bundleClass: TestingStuffTests.self, filename: "test.json")
        
        measureBlock {
            let array = json?.array
            if let array = array {
                let _: [Person] = array.map { object in
                    let jsonPerson = object as THGCodable.JSON
                    return try! Person.decode(jsonPerson)
                }
            }
        }
    }
