SafeIterator

SafeIterator places a simple stream on top of an iterator, returning Option-wrapped instances from the underlying iterator. When the stream is exhausted, the Iterator stream returns None. Differences from a plain Iterator include:

- An SafeIterator will not throw an exception if you try to read past the end of it. Instead, it will just keep returning None.

Example of use with a string:

import grizzled.parsing.SafeIterator

val s = ...
val istream = new SafeIterator[Char](s.elements)
