adding a few comments

[zargold]

is this the correct style of comments desired?

I like the jsdoc comments style like so :

/**
* Determines whether first input is the same instanceof second input.
*
* @param {any} left: first-input
* @param {any} right: second-input
* @return {boolean} isInstance: whether first is an instance of second.
*/

But crypto.js is a library I found elsewhere so I have no idea if your comments are correct. Don't worry about commenting that file at this point.

Note that PR #13 will be merged before the others once it is fully reviewed. This may need a rebase at that time.

Thanks!

Maybe hold off on any other commenting until then.

Please review and rebase this PR, due to a major refactor of the code was recently merged.

Thanks!
