% Description:
% Sets various attributes of the PR-670.
%
% Arguments are attribute, value pairs
%
% Supported attributes
%   'GetAperture' -- Get apperture.  Values are numeric in degrees
%   'SetAperture' -- Set apperture.  Values are numeric in degrees
%    Allowable values: 1 , 0.5, 0.25, 0.125
