Extra search algorithm information & UI audio

Detailed information has been implemented into the newest MAPV update for each search algorithm. This extra information gives a high level explanation about what each algorithm is, does, and how it could be used for practical use in games.

Another addition is audio for UI elements and path completion. I was a bit hesitant on adding audio, since it didn't add anything substantial to the functionality of the app, but app also lacked general feedback when using the visualiser. Ultimately I feel now that audio does give the app some more life, even if it isn't strictly necessary.

One benefit of adding audio was more personal. Since this app is all created, relatively, from scratch; that is, there is no engine or framework, audio functionality was something that I needed to implement myself, and since I'll need to add it into future projects anyway, I thought that adding it here , in a small-scale project was a good idea that would allow me to get my feet wet in learning general low level audio concepts.

There will most likely two more updates. One major, that will include what I call "cost painting". This will allow costs to be added to nodes. Dijkstra's and A* are the algorithms that will see a marked difference with this new feature. The other feature for the major update will be saving and loading maps user created maps.

The last update will be smaller: polishing the UI, adding additional stats for the searches, such as: how many nodes were checked and how long the path is in nodes, and other QoL changes.
