Description

Add support for class and package based namespacing in ComponentConfigurator:

• Add a new method to ComponentConfigurator - detectConfiguration()
• When the caller does not provide a Config or a path to detectConfiguration, get fancy:
• Look for the fields declared by the component POJO class on each of the following:
• the SimpleClassName
• the CanonicalClassName
• each ancestor package of the CanonicalClassName, longest to shortest
• if a field is specified at more than one package/class level, the class or longest package ancestor takes precedence.

Write sufficient unit tests to demonstrate that this is working as intended.
