Improve the documentation

[rezoner]

I believe that this is a great library. Maybe even the best way to work with matrix math. I enter the docs and I can tell that it has a hell lot of useful stuff that I am looking for - but it misses the one basic thing - at least the simplest example of how to use it. Is it a functional library? Is mat2 a constructor?

Of course I dwelled into the source and figured that out - but that's not the point and most of people won't.

Thank you for making this library and thank you in advance for making it more accessible.

@toji I would be willing to write a bunch of examples. However, I'm not sure where those examples should be? In a .md file? In the README.md file? Or should the home page a have a link to a .html file/website with a bunch of examples?

This issue is up for grabs. Ideally, a few simple examples would be in the Readme file.

And this picture would be quite nice

Since there are three entry points (sites where the google search leads for the first time) in my opinion they all should contain the copy paste of the short examples.

This is the frontpage, documentation and readme.md

The examples should display how to create a new vector/matrix and briefly explain the nature of (target, source, ...) pattern in most of the methods. In other words explain that this way one can decide to leave the source intact or mutate it.

Another note regarding the docs: It might be nice to automatically load the library so that anyone can quickly test it out in the browser console.
