Organize the GitHub repository

[ect123]

There are some things that can improve the organization of the repository.

• If you click on the bulleted links on the main README, they goes to documentation not the map. Maybe use two links - one for map and the other documentation, for example "Composer Map [README]
• List the repository contents in tree format in main README. This should be the last task completed.
• The composers map has an extra directory level, which makes the URL string unnecessarily long and unpredictable. I would suggest moving the composers-map folder's content up one directory level, and changing any affected relative paths in the map document.
• Delete the file timeline/timeline-boilerplate.html (Moved into README.md)
• Rename the file timeline/timeline-1.html to timeline/timeline.html (now timeline/index.html).
• Might be good to package up the two files used for the timeline graph into one folder.

For the composer map, all files pertaining to the latest version is stored in the testing_0724 directory,

I have moved testing_0724 to composers-map, and moved composers-map to composers-map-old. (I hope that doesn't mess up anyone's current progress). This is done with commit 900b68b

The composers map has an extra directory level, which makes the URL string unnecessarily long and unpredictable. I would suggest moving the composers-map folder's content up one directory level, and changing any affected relative paths in the map document.

This is good to do, but I will wait a few days to do if no one has problems with the current change (the new styling of the composers list should be visible from the https://maps.polyrhythm.humdrum.org webpage link to the composers map now.

Rename the file timeline/timeline-1.html to timeline/timeline.html

Commit a97fd76 does this, but the URL is further simplified to either:

https://maps.polyrhythm.humdrum.org/timeline

or

https://maps.polyrhythm.humdrum.org/timeline/index.html

Commit 8927672 deletes timeline-boilerplate.html, but it is actually embedded now into the README.md file.
