See:
Description

Interface Summary
IObservableValue: A value whose changes can be tracked by value change listeners.
IValueChangeListener: Listener for changes to observable values.
IValueChangingListener: Listener for pre-change events for observable values.
IVetoableValue: An observable value whose changes can be vetoed by listeners.

Class Summary
AbstractObservableValue: This class is thread safe.
AbstractVetoableValue: This class is thread safe.
ComputedValue: A Lazily calculated value that automatically computes and registers listeners on its dependencies as long as all of its dependencies are `IObservable` objects.
DateAndTimeObservableValue: An `IObservableValue` < `Date` > which supports scenarios where the date and time are presented as separate elements in the user interface.
DecoratingObservableValue: An observable value which decorates another observable value.
DecoratingVetoableValue: An `IVetoableValue` decorator for an observable value.
DuplexingObservableValue
SelectObservableValue: An observable value which behaves similarly to the <select> and <option> HTML tags.
ValueChangeEvent: Value change event describing a change of an `IObservableValue` object's current value.
ValueChangingEvent: Value changing event describing a pending change of an `IObservableValue` object's current value.
ValueDiff
WritableValue: Mutable (writable) implementation of `IObservableValue` that will maintain a value and fire change events when the value changes.
