function pstruct = subget(hnd,props)
% subget  - get a list of properties as a struct
%
% this function simplifies getting multiple properties from
% MATLAB's graphics handle objects.
%
% FORMAT:       propstruct = subget(handle, props)
%
% Input fields:
%
%       handle      Nx1 graphic handles
%       props       either a single string or a cell array or
%                   strings naming properties of the handles
%
% Output fields:
%
%       propstruct  Nx1 structure array with property contents
%
% See also get.
