function obj = loadobj(B)
%LOADOBJ Load filter for timer objects.
%
%   OBJ = LOADOBJ(B) is called by LOAD when a timer object is 
%   loaded from a .MAT file. The return value, OBJ, is subsequently 
%   used by LOAD to populate the workspace.  
%
%   LOADOBJ will be separately invoked for each object in the .MAT file.
