Controls the field name that will be used in pdx for a field being auto serialized. Override
this method to customize the field names that will be generated by auto serialization. It
allows you to convert a local, language dependent name, to a more portable name. The returned
name is the one that will show up in a {@link PdxInstance} and that one that will need to be
used to access the field when doing a query.
<p>
The default implementation returns the name obtained from <code>f</code>.
<p>
This method is only called the first time it sees a new class. The result will be remembered
and used the next time the same class is seen.

@param f the field whose name is returned.
@param clazz the original class being serialized that owns this field. Note that this field may
       have been inherited from a super class by this class. If you want to find the class that
       declared this field use {@link Field#getDeclaringClass()}.
@return the name of the field
