IResult vs PResult

[9999years]

The documentation for IResult and PResult is very similar and doesn't explain how they're different. Practically I can see that IResult contains the remaining input in its Ok branch, but I'm not sure when this is used or if I should return it from my parsers (I'm assuming no because the tutorials use PResult).

Also, I'm not sure what the mnemonic for IResult is. I can tell that PResult is a parser result (the docs could spell this out, too), but is IResult an intermediate result? Input result, for its InputError?

Finally, the docs for PResult say that "By default, the error type (E) is ErrorKind", but the actual error type is ContextError. (The tutorials don't reflect this either.)

I've tried to cover the answer for this in #328
