/**
* Implementation of DynaBean that wraps a standard JavaBean
* instance, so that DynaBean APIs can be used to access its properties,
* though this implementation allows type conversion to occur when properties are set.
* This means that (say) Strings can be passed in as values in setter methods and
* this DynaBean will convert them to the correct primitive data types.
*
* IMPLEMENTATION NOTE - This implementation does not
* support the contains() and remove() methods.
