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.
