I am open to hearing any suggestion as to other questions which could be covered in the collection. Such suggestions need not be basic. Please read the pdf file prior to use. Also the contents.m file contains brief descriptions of each GUI.

Please email me if an error is found, either in the documentation or coding. Thanks.
