Apply a lowercase to all the mio names.

Fix for #679.

Thanks for contrib 👍

I think that "Mio" should be treated as a proper noun at this point (capitalizing the first letter).

Capitalization has changed over time due to what the "Mio" name meant. It has converged to being a proper noun.

Maybe we should update the references in the README too. There are a few different ways the lib is referred to in there:

• mio
• mio
• MIO

[carllerche]

Updating the README would be good too, however, mio refers to the crate literal (what is imported).

[dethoter]

Closing this PR since changes are senseless.

[KodrAus]

@dethoter I don't think these changes are senseless, and am glad you got stuck in and made them! It's subtle but significant to have consistent naming.

[carllerche]

Yeah, I don't think it is senseless either, it is pretty subtle :)

[dethoter]

Apologize, I haven't been clear enough. @carllerche decided that

"Mio" should be treated as a proper noun

Here I changed Mio to mio that's incorrect according to accepted decision. So exactly this PR is senseless. I'll open a new one to update README.
