Class DynaBeanPropertyMapDecorator
 Decorates a DynaBean to provide Map behavior.
 
 The motivation for this implementation is to provide access to DynaBean properties in technologies that are unaware of BeanUtils and
 DynaBeans - such as the expression languages of JSTL and JSF.
 
 This can be achieved either by wrapping the DynaBean prior to providing it to the technology to process or by providing a Map accessor method
 on the DynaBean implementation:
 
 
         public Map<String, Object> getMap() {
             return new DynaBeanPropertyMapDecorator(this);
         }
 
 
 This, for example, could be used in JSTL in the following way to access a DynaBean's fooProperty:
 
- ${myDynaBean.<strong>map</strong>.fooProperty}
Usage
 To decorate a DynaBean simply instantiate this class with the target DynaBean:
 
- Map<String, Object> fooMap = new DynaBeanPropertyMapDecorator(fooDynaBean);
 The above example creates a read only Map. To create a Map which can be modified, construct a
 DynaBeanPropertyMapDecorator with the read only attribute set to false:
 
- Map<String, Object> fooMap = new DynaBeanPropertyMapDecorator(fooDynaBean, false);
Limitations
 In this implementation the entrySet()</code>, <code>keySet()
    and values() methods create an unmodifiable
    Set</code> and it does not support the Map's <code>clear() and remove() operations.
