Update file names, navigation, and Open in MATLAB Online

1) Remove 'programming' from the beginning of each script name and update all
   links accordingly
2) Add an .html navigation page called Overview.html for use on Desktop
3) Add a link to "Open in MATLAB Online" to the README and reorganize
   the README to make sense of the multiple options for accessing the
   information
4) Add *.asv to the .gitignore
