Extended Iterators

Some useful extensions to rust's iterators.

Modules

• buffered: Maintains a buffer of items in memory.
• interleave: Interleaves two iterators.
• logging: Unwraps Result items, debug printing any errors.
• stateful: Maps a function to items, but allows passing a struct to be used as "working" state. Eg. when the function needs to allocate a lot of memory to compute intermediate values.
• threaded: Multi-threaded map that maintains the ordering of items in the iterator.
• stateful_threaded: Combination of the stateful and threaded modules.
