State: open

A Signal is similar to publisher except it is:
Not using dataflow model, but is a variable that always has a value and can be read at any time.
Event handlers are triggered on changes, not on new data published.
Changes are guaranteed to be delivered to subscribers.

Can be used to provide information such as current state or values that are only required to be read in certain situations.
