		/**
		* An ISoundTriggerMiddlewareService decorator, which adds logging of all API calls (and
		* callbacks).
		*
		* All API methods should follow this structure:
		* <pre><code>
		* @Override
		* public @NonNull ReturnType someMethod(ArgType1 arg1, ArgType2 arg2) throws ExceptionType {
		* try {
		* ReturnType result = mDelegate.someMethod(arg1, arg2);
		* logReturn("someMethod", result, arg1, arg2);
		* return result;
		* } catch (Exception e) {
		* logException("someMethod", e, arg1, arg2);
		* throw e;
		* }
		* }
		* </code></pre>
		* The actual handling of these events is then done inside of {@link #logReturnWithObject(Object,
		* String, Object, Object[])}, {@link #logVoidReturnWithObject(Object, String, Object[])} and {@link
		* #logExceptionWithObject(Object, String, Exception, Object[])}.
