Document

Wrap the given BeanInfo instance; copy all its existing property descriptors locally, wrapping each in a custom SimpleIndexedPropertyDescriptor indexed or SimplePropertyDescriptor non-indexed PropertyDescriptor variant that bypasses default JDK weak/soft reference management; then search through its method descriptors to find any non-void returning write methods and update or create the corresponding PropertyDescriptor for each one found.

Usage
