Decoratable Converters

[mike4git]

Scenario 1:

Sometimes you want to convert several different objects in the same manner, means same target and the same populators, but a smaller part of it will be populated additionally with some other populators.

Scenario 2:

You want to offer (e.g. in a bundle) a Converter with target (interface) and Populators which should be extendable with some more specific Populators in the app which is using the bundle.

Both scenarios solved by an easily decoratable Converter (or a documented way of how to use the given artefacts) would be handy to use.
This is the goal of this issue.
