PatternTesting Runtime (patterntesting-rt) is the runtime component for
the PatternTesting framework. It provides the annotations and base classes
for the PatternTesting testing framework (e.g. patterntesting-check,
patterntesting-concurrent or patterntesting-exception) but can be also
used standalone for classpath monitoring or profiling.
It uses AOP and AspectJ to perform this feat.
