function [cs] = NewCs(Name, win, p1, p2, p3, p4, p5)
%
%   [cs] = NewCs (Name, Con, P1, P2)
%
%Purpose:
%   Create a command structure for passing to TellAfni
%   
%   
%Input Parameters:
%   Name: Name of command, see AFNI's README.driver for all possibilities
%         Example: SET_THRESHOLD 
%         To see a list of commands, try the function TellAfni_Commands
%         To start AFNI, use the special Name: 'start_afni'
%   Con : Index of controller where command is applied.
%         Choose from 'A' to 'J'. Default if win = '' is controller 'A'
%   P1  : First parameter passed to command. This can include the
%         controller index in the form A.  See AFNI's README.driver
%         for information and Test_TellAfni for examples.
%   P2  : All other parameters to pass to command. This would include
%         any second parameters plus options.
%Output Parameters:
%   cs  : Returned structure to feed to AFNI with TellAfni
%       .err: Error flag
%       .w  : AFNI controller
%       .c  : AFNI command (Name)
%       .v  : AFNI command value
%   
%
