Move to stateless implementation of Streams to prevent dreaded FRP 'time leaks'
Use private module scope rather than nested class for Map
Remove unused instance variables
Readd new line
Merge pull request #5 from seadowg/master

Switch to push based implementation
Merge two streams.
Another merge test.

This time, testing +1/-1. Neat.
Adding #on_value.

This allows you to have a callback when some kind of value
comes down the stream.
Actually yield the event.

I forgot to properly yield the event. Oops
Add Inject#on_value.

This is useful too. Duck typing.
fix warning re: ambiguous argument
Use varargs for constuctor.

This way is much nicer.

.merge is basically an alias for .new at this
point, but I like the semantics. If I have two
things, I use varargs in the constructor, and
if I have two streams, I use merge to merge
the two.
Add #map_stream.

This allows you to do this common case:

    .map do |event|
      case event
      when :+
        1
      when :-
        -1
      else
        0
      end
    end

This turns into:

    .map_stream(:+ => 1, :- => -1, :default => 0)
Update README with more stuff
Fix install instructions.
One more install fix. whoops
Add #select

Woo. More of Enumerable.
Allow for multiple callbacks to be registered on a Stream
Allow multiple callbacks to be registered on Inject
