/**
 * 
 * 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.
