Add some basic functional tests around direct use of NSURLConnection before starting to introduce Category/Swizzling magic.
Clean-up implementation of TestConnectionDelegate and test_connection_delegate* methods.

build_and_run_functional_tests.sh fails due to weird SSL stuff, though tests are fine in Xcode.
Swizzling NSURLConnection methods relevant to request execution.

Does not integrate with WNGLogger yet.
Add basic record start+finish of synchronous requests.
Add docs supporting removal of loggingDelegates.
Implement first pass of instrumenting asynchronous requests.
Construct a metric name based on the request's host.

Re-instrument synchronous approach with local variables.  Extract and use method to convert a NSURLRequest to a metric name.
Document and test convertToMetricName.
Implement rest of NSURLConnectionDataDelegate protocol
Update respondsToSelector checks to match the delegated method call.
Create a unit test for LoggingConnectionDelegate.
Enhance unit LoggingConnectionDelegateTests
1. fix-up previous commit to create a unit test for LoggingConnectionDelegate
2. add unit test to verify delegation of NSURLConnectionDelegate:connection:didFailWithError
Clean-up mocking constructs a little bit.
