function [sim_param_changeable, sim_param_unchangeable, sim_state_prototype] = DefineStructures
% DefineStructures specifies the prototype structures.
%
% The calling syntax is:
%     [sim_param_changeable, sim_param_unchangeable, sim_state_prototype] = DefineStructures
%
%     sim_param_changeable = Prototype structure containing simulation parametes that can be changed
%     sim_param_unchangeable = Prototype structure containing simulation parametes that cannot be changed
%     sim_state_prototype = Prototype of structure containing simulation results
%
%     Note: See readme.pdf for a description of the structure formats.
