Housekeeping: Added a .gitattributes file; updated .gitignore.

The .gitattributes file is for use with some Python scripts that I use to update source code tags.  The .gitignore changes exclude some Python detritus.

Minor updates were made to the comments in the modules to make them a

in more than 10 years.
