Functionality needed for Bean introspection, required for detecting
accessors and mutators for Beans, as well as locating and handling
method annotations.


Beyond collecting annotations, additional "method annotation inheritance"
is also supported: whereas regular JDK classes do not add annotations
from overridden methods in any situation. But code in this package does.
Similarly class-annotations are inherited properly from interfaces, in
addition to abstract and concrete classes.
