The concept of parameter in the JeVois framework embodies wrappers around a single value of any type, with associated documentation (description), default values, possible specification of valid values, accessor functions to obtain or change the value, and optional callback functions that are triggered when the value is changed. Parameters are intended to be used in objects that inherit from Component. The goal of parameters is to expose parameters of a given vision algorithm in such a way that any piece of code that is using that algorithm will automatically inherit and expose these parameters.
How to explore this documentation module:
The other classes in this documentation module are mainly for support of the above ones.
ParamName is the name chosen for the parameter. A new class type will be created with that name, so it must be syntactically correct as a class name. ParamType is the type of the parameter value. The remaining arguments are passed to the constructor of jevois::ParameterDef<T> with T=ParamType.

In this version with callback, a pure virtual method is included in the new class that is defined, with the following signature:
The host class (typically, a Component) that inherits from Parameter<ParamName> must implement an override of this function. A compile-time error will be issued if that override has not been implemented.
