/**
* Convenient class for building up pointcuts.
* All methods return ComposablePointcut, so we can use a concise
* idiom like:
*
* Pointcut pc = new ComposablePointcut().union(classFilter).intersection(methodMatcher).intersection(pointcut);
*
* There is no union() method on this class. Use the Pointcuts.union()
* method for this.
