Commit Message

Refactored `seq` again; also added the `lim` function

The signature of `seq` is now much less smelly. The `length`
field is still around, for those lazy sequences that *do* know
their length up front (range, for instance.)

The `lim` function was added as an abstraction to the common
case of having functions that should only be callable a set
number of times. This makes it very easy (and safe!) to
implement bounded sequences, by simply limiting the number of
times the `next` function can be called. This is also used
within `seq` to limit calls to `next` in those cases that a
length is specified and the collection is lazy.

A `seq` can be lazy, not report a length, and *still* be
bounded; as is shown by `take` which doesn't report its length
even though it possibly could. This is because while it's true
that `take` has an upper bound of `n`, it may actually be less
than that in case the underlying sequence has fewer items.
I figured the principle of least surprise dictates in this
case that `take` should simply have an undefined length.
