Summary: Adding incremental instrumentation

Initial Comment:
We are developing a prototype Eclipse plugin for Cobertura (it is under testing now and may be open sourced soon). For such a plug-in to be useful, Cobertura needs the ability to instrument only classes that has been changed since the last instrumentation. We noted that Emma has this feature.

Here is the detail of the issue:

Every time I launch a test, I would instrument the classes and generate a coverage report after the execution. The problem is that every time I instrument, Cobertura would re-instrument the whole classpath, even
though only a few classes changed since the previous instrumentation - this is a big performance drawback when Cobertura is used in an interactive mode. There are many projects that takes about 1 minute to be fully 
instrumented.
