// In order to avoid a circular dependency problem at runtime between BaseObservableValue
// and the classes that extend it, it's important that:
//
// 1) It always remain the first module exported below.
// 2) Anything that imports any of the classes in this module
//    ONLY import them from this index.ts file.
//
// See https://medium.com/visual-development/how-to-fix-nasty-circular-dependency-issues-once-and-for-all-in-javascript-typescript-a04c987cf0de
// for more on why this discipline is necessary.
