WIP on using CCI to replace reflection - miles to go yet
Grouping now working for instrumented methods, and nested types working better for Cci
Removed old InstrumentationDiscoverer, disabled compilation of test classes that relied upon it, renamed InstrumentationTarget2 to InstrumentationTarget
Generics and namespacing handled better, especially for CCI
Improved (reverted, really) handling of nested types to get correct instrumentation context
Adding ability to pull InstrumentAttributes from IAssembly instances, for subsequent use in assy-level instrumentation config
