% REOGANIZE rearranges a ssm object for fast input to BODE, SIMULATE, PSD.
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%
% DESCRIPTION: rearranges a ssm object for fast input to BODE, SIMULATE, PSD.
%
% CALL:    sys = reshuffle(sys, plist)
%
% INPUTS:
%         'sys'      - ssm object
%         'plist'    - plist object
%
%  The inputs/states/outputs can only be indexed using a cellstr containing
%  block names or port names.
%  Then the object can be passed to BODE, SIMULATE, PSD, CPSD, RESP with
%  the option "rearrange" turned to "false". These functions will run
%  significantly faster.
%
% OUTPUTS:
%
%        'sys' - a ssm object.
