+% arguments: 
+%   interfaceName: a JEInterface instance needs to know its own
+%       name as a String to allow callbacks from Java.
+%   fhandle: a function handle defining the optimization target.
+%   range: a 2 x dim array defining the solution subspace with lower and
+%      upper bounds.
+%   optset: (optional) an optimset struct defining optimization parameters,
+%       especially tolerance and maximum function calls. Defaults to the
+%       JavaEvA default values.
+%   defaultArgs: (optional) additional constant argument to the target
+%       function, empty by default.
