Detailed Description

Extended plugin base class with automatic parameter / program handling.

Two template arguments must be provided:

the implementation type itself to access static data (parameter descriptors / programs) (this pattern is known as the curiously recurring template pattern (CRTP))
number of outputs

Assumptions:

first program is enabled by default -> default parameters should match program settings
