Alchemist.register broken in recent version

[Nkburdick]

I'm getting a no method error when trying to register new units

irb(main):005:0> Alchemist.register(:volume, [:dash, :dashs], 0.125.teaspoons)
NoMethodError: undefined method `register' for Alchemist:Module
    from (irb):5
    from /usr/local/var/rbenv/versions/2.0.0-p247/bin/irb:12:in `<main>'

Alchemist.register has moved to Alchemist.library.register. This needs to change in the documentation. Additionally there's an additional step with register I'd like to remove

irb(main):001:0> require 'alchemist'
=> true
irb(main):002:0> Alchemist.setup(:volume)
=> Numeric
irb(main):003:0> Alchemist.library.register(:volume, [:dash, :dashs], 0.125.teaspoons)
=> [:dash, :dashs]
irb(main):004:0> Alchemist.setup(:volume)
=> Numeric
irb(main):005:0> 1.dash.to.teaspoons
=> #<Alchemist::Measurement:0x007f8974b105f8 @value=0.125, @unit_name=:teaspoons, @exponent=1>

The second Alchemist.setup shouldn't be required.

Changed master to delegate from Alchemist.register to Alchemist.library.register and got rid of the additional call to setup.

Thanks!
