1.0.0 (10/27/2010) 
     Original published version of the program

1.0.1 (03/29/2011) 
     Program recompiled with PowerBASIC Console Compiler Version 6.0 to run slightly faster.

1.1.0 (05/23/2011) 
     The constant term can now be toggled on and off (A command).
     A new bias term has been added and can be toggled on and off (B command).
     The default values leave the program as it was previously.

1.1.1 (05/25/2011) 
	Fixed a slight bug in the previous version.

1.1.2 (07/27/2011) 
	A slight change in the training protocol now helps prevent getting trapped in a local optimum.

1.1.3 (08/02/2011) 
	Additional changes in the training protocol now further discourage getting trapped in a local optimum.

1.2.0 (08/26/2011) 
     A prune command (P) has now been added to zero out weights for which |a(i,j)*b(i)| < 10^-p.
     Neurons are now less likely to saturate.
     Keyboard commands are now accepted when the graphics window has the focus.
     The commands in the help screen have been alphabetized.
     The program version number is now displayed in the window captions.
     A withhold command (W) has been added to control the number of data points withheld for testing.
     A save command (S) has been added to control the number of predicted points to save to *.net file.
     Neurons and dimensions are now progressively and alternately added.

1.2.1 (09/22/2011)
     A minor change in the training protocol was made.
     The training now allows negative values of b(i).
     A bug was fixed in the out-of-sample prediction when b(0) is nonzero.

1.2.2 (09/30/2011)
     The Lyapunov exponents now wrap at the end of the line so that they all can be seen.

1.2.3 (12/01/2011)

     The program now defaults to using six neurons instead of four.

1.3.0 (6/6/2012)
     Rather than beep when an improved solution is found, the program now sonifies the attractor.
     The sound can be toggled on and off or played with the S command.

1.3.1 (7/27/2012)
     Neurons and dimensions are no longer added one-by-one.
     Several changes were made to the training protocol.

     Periodicity testing for the model equations was added.

1.3.4 (6/25/2016)
     Minor cosmetic changes were made.

1.3.5 (7/22/2016)
     A test for quasiperiodicity was added.
