/**
 *
 * Port of [RemoteData](https://github.com/devexperts/remote-data-ts/blob/master/src/remote-data.ts)
 *
 * Represents a value of one of four possible types (a disjoint union)
 * An instance of [RemoteData] is either an instance of [Initial], [Pending], [Failure] or [Success]
 *
 * A common use of [RemoteData] is as an alternative to [Either] or [Option] supporting initial and pending states
 *
 * Note: [Initial], [Pending] and [Failure] are commonly called "Left" part.
