Allow corporate users to swap in implementations of logging, profiling etc

[ricksbrown]

Assumptions

1. This software should include and facilitate logging, profiling, configuration...
2. The actual implementations of these concerns should be "swappable", for example FooCorp should be able to use the FooCorp profiling library, and BarCorp should be able to use theirs.
3. Annotations are frequently not going to provide enough granularity to solve this problem

** Thoughts **

• Logging, SLF4J?
• Profiling: Create an Interface and dummy implementation. Users can write adaptors that implement the interface and pass profiling calls to their implementation
