Detailed Description

Base class for all Providers.

It implements listener (observer) pattern (can be observed by Receiver).

Subclasses should only implement operator()(...) which returns provided value, or throw NoValue exception. Receiver (for given provider type) can be easy implemented by inherit Receiver class template.
