Benchmark clear() behavior with OOP handle

Examine Matlab's "clear" behavior with different handle reference configurations.

Create N handle objects, store 1-3 references to each.
Order of object creation, number of references, and configuration of references all have drastic impact on "clear" time as function of number of objects. Times range from flat, to linear, to quadratic.

Using a simple handle class:
% % classdef simpleHandle < handle
% % properties
% % ref1;
% % ref2;
% % end
% % methods
% % function self = simpleHandel
% % end
% % end
% % end
