[Grok-dev] Naming of grok.provides

So far "provides()" is just used for LocalUtility, right? As such,
it'll likely be in close proximity to the class declaration where it
will be embedded.

When thinking about what term to choose I tend to think of how the
code will read as a whole.

In the case "register_for(ISomething)" (or
"registers_for(ISomething"), it will likely be read closely after
"class MySomething(LocalUtility)", so it pops up in my mind as
"MySomething, a local utility, is being registered for

The nice thing about it is that it bypasses the whole
implements/provides discussion. And in the case of utilities, this is
really all that matters. When you're using an utility, you're not
doing adaptation (explicitly), you're just asking for the C.A. do give
you the closest ISomething utility it can find.

Of course proficient C.A. users will have to understand the
implements/provides distinction eventually, but IMHO, if we can give
the above emphasis in the documentation we can avoid the concept
confusion and the explanation at this point.

Between the above options I'm +0 for  "registers_for" over
"register_for" and +1 to any of them over "provides". I also think the
former options will work better than the later even if we eventually
reuse it for other base classes than LocalUtility.

Cheers, Leo
