To use: move the maxiLib.js file from the maxiLib folder to an appropriate location and include using the <script> tag right now.
If you want to use without webAudio API setup for you, include maxiLib_noWebAudio.js. You can still include the maxi_webAudio file (from the src/js folder) after this and all will function as usual.
Examples are in maxiLib/maximilian_examples_web.
