Arrayr
======

Module to use for letting attributes automatically return arrays for 
comma separated values

Specify which attributes that should return array as values
and access the value by suffixing the attribute with "_multiple"

If a getter and setter doens't exists this module will create them for you.

Example 
-------

  class Foo
    include Arrayr
    attr_arrayr(:bar)
  end
  
  foo = Foo.new
  foo.bar = "zoo, zum"
  foo.bar_to_a  => ["zoo", "zum"]
