Get this show on the road

Get this thing off the ground:

[x] Get csound-wasm working.
[x] Install csound-wasm.
[x] Do a proof of concept for generating an always-playing score, and using a shader to visualize the music.
[x] This in turn requires, for always-on pieces, some means of synchronizing score generation in segments or loops. It will not do to generate an infinitely long score in one go.
[x] Do a proof of concept for using a shader to generate a score.
[x] This in turn requires integrating chord spaces and scales while generating scores from sampled visuals.
[x] Provide examples with basic user controls, including at least audio level and reverb.
[x] Enable saving controls to local storage, restoring them from local storage, and restoring them from defaults. Also, copy to and from the system clipboard.
[x] Refactor code to preserve encapsulation. This can be done, I think, simply by using different <script> elements and commenting them. Actually, not doing this due to the mixture of languages (HTML, JavaScript, WebGL/GLSL, Csound. I simply put in a comment.
[x] Improve GitHub pages.
[x] Fill out user controls for Nos. 1 and 2.
[x] Fill out help, credits, and resources for Nos. 1 and 2.
[x] Change No. 1 to use tempo.
[x] Use only local resources from the server root.
[x] See if there is anything to do about the reverb slap in No. 1.
[x] Decent default parameters. They need to take effect the first time a piece is loaded.
[x] No. 2 sometimes hangs after a while. Can't reproduce in debugger.
