%HASTAG  tests if an object has a specific tag
%
% BOOL = HASTAG(OBJ_HANDLE,STR)
% 
% Tests if the object corresponding to OBJ_HANDLE has the tag STR.
% When OBJ_HANDLE is an array of handles HASTAG returns a logical array of
% the same size.
% 
% Rem: In order for this to work properly, the object's tag field must be a string 
% containing keywords (or tags) separated by commas.
