function Value = pvget(RespObj,Property)
%PVGET  Get values of public Response Object properties.
%
%   VALUES = PVGET(RespObj) returns the values of all public 
%   properties of RespObj in the cell array VALUES.
%
%   VALUES = PVGET(RespObj,PROPERTY) returns the value of the
%   single property with name PROPERTY.  The string property
%   must contain the true property name.
%   
%   See also GET.
