[8]1%'update_obj': update the object graph representation and its projection field, record it in the uvmat interface
2%-------------------------------------------------------------------
3%Object=update_obj(UvData,IndexObj,ObjectData,PlotHandles);
4%
5%OUTPUT:
6%UvData: data to be stored as 'Userdata' on the uvmat interface
7%IndexObj: object index for a new object added to the list in UvData
8%   the function updates UvData.Object{IndexObj}, and possibly adds a new plot (UvData.Plane or Line) in the list atached to the interface
9%
10%INPUT:
[71]11%UvData: structure stored as 'Userdata' on the uvmat interface, it contains
12%    .Object{1},{2}... description of all the projection objects
13%    .Object{iview}.plotaxes: axes for the plot of the field projected on this object
14%    .Object{iview}.HandlesDisplay(ih): array of handles for plots representing the object #iview in the field #ih
[8]15%IndexObjIn: object index for an existing objects stored in UvData
16%ObjectData: structure containing the input object properties
[71]17%       .Style: style of the object: 'line', 'rectangle'...
18%PlotHandles: structure containing the handles of the plotting parameter buttons on the uvmat or view_field interface
