Detailed Description
A class that can be used to implement a "busy" indicator.
The exact form of the busy indicator is unspecified. It could be a "spinner" cursor in a GUI context, for example.
This base class provides a "null" implementation, and can be overridden for specific behaviours.
THe busy-ness semantics are defined by this object's lifetime.

◆ FACTORY
| using BUSY_INDICATOR::FACTORY = std::function<std::unique_ptr<BUSY_INDICATOR>()> |
A factory function that returns a new busy indicator.
Because BUSY_INDICATORs are RAII objects (i.e. the busy-ness is defined by the object's lieftime), it's convenient to pass a factory function for a client to be able to make a busy indicator when needed.
