                  2 %HASBEHAVIOR sets(enables/disables) or gets behaviors of hg objects
                  3 %
                  4 % HASBEHAVIOR(H,NAME,STATE) sets the behavior named NAME for the 
                  5 % hg object with handle H to STATE (true or false). The NAME
                  6 % is case-insensitive. The name 'legend' is used by the LEGEND
                  7 % command to enable or disable showing the object in a legend.
                  8 % HAS = HASBEHAVIOR(H,NAME) returns the boolean value for the
                  9 % behavior NAME of H.  If the behavior has not been previously 
                 10 % set for H, then 'on' is returned.
