Reactive<T> class

A Reactive class that represents a value that can be observed.

The value can be updated, and the change is propagated to its listeners. _middlewares is a list of FluxivityMiddleware instances that can be used to add hooks or intercept the update process. _value is the initial value of the Reactive instance.
