%'update_obj': update the object graph representation and its projection field, record it in the uvmat interface
%-------------------------------------------------------------------
%Object_out=update_obj(UvData,IndexObj,ObjectData,PlotHandles);

%OUTPUT:
% Object_out= cell array of structures containing the properties of the existing objects     .
%
%INPUT:
%UvData: structure stored as 'Userdata' on the uvmat interface, it contains:
%    .Object{1},{2}... description of all the projection objects 
%    .Field , the current input field to be projected on the object
%    .Object{IndexObj}.DisplayHandle_uvmat: handles of the object plot on uvmat, =[] if it does not exist
%    .Object{IndexObj}.DisplayHandle_view_field: handles of the object plot on view_field, =[] if it does not exist
%IndexObj: object index of  UvData.Object correspopnding to the updated object
%ObjectData: structure containing the input object properties to be attributed to the object #IndexObj
%       .Style: style of the object: 'line', 'rectangle'...
%PlotHandles: structure containing the handles of the plotting parameter buttons on the uvmat or view_field interface
