/** Really simplistic XPropertySet helper for properties.
This class provides easy access to properties , referenced via
ASCII strings . The name / property modification callbacks pairs
are passed into this class via a vector . Each time a property
is set or queried , the corresponding getter or setter callback
is called .
Use this class as a delegate for the corresponding
XPropertySet methods , and take care of UNO XInterface and lock
handling by yourself .
The core responsibility of this class is the name / value
mapping for property sets .
