// This type is used to represent properties in messages that support it.
// It is a free-form object so the application can set any value it sees fit but
// a few helper method are defined to make it easier to instantiate properties with
// common fields.
// Here's a quick example of how this type is meant to be used:
//
//	analytics.Page{
//		UserId: "0123456789",
//		Properties: analytics.NewProperties()
//			.SetRevenue(10.0)
//			.SetCurrency("USD"),
//	}
//
