Every Now And Then
==================

It's quite simple, really - it lets you do something every specified interval of time. When supplied with a block, it
yields the iteration count (starts at zero).

It requires 'active_support/time', so as to allow time intervals to be specified as 5.seconds, 6.7.days, etc. The 'every'
method accepts integers or floats.

If the operation inside the block takes longer than the specified interval, then the next iteration will begin
immediately after the last.

To exit, simply break out of the loop.

Examples
========

    require 'enat'

    every 4.2.minutes do |i|
      puts "wheee! i've done this #{i} times!"
      break if i > 5
    end

Installation
============

    $ gem install enat
