)

func main() {
	parameters := make(map[string]string)
	parameters["boolean"] = "true"
	parameters["float"] = "1.2"
	parameters["integer"] = "11"
	parameters["string"] = "value"

	properties := proper.NewProperties(parameters)
	fmt.Println(properties.BooleanParam("boolean", false)) // true
	fmt.Println(properties.FloatParam("float", 0))         // 1.2
	fmt.Println(properties.IntegerParam("integer", 0))     // 11
	fmt.Println(properties.StringParam("string", ""))      // value
