Declares the <tt>ActiveMerge</tt> module for extending ActiveRecord models.

The module contains the <tt>merge_all</tt> class method for merging
class instances into the first one.

When merging a list of instances:
* all "has_many" relatives are reattached to the instance with the lowest id
* all the instances except for the first one (with the lowest id) are deleted

== Example

    class Post < ActiveRecord
      extend ActiveMerge
      has_many :comments 
    end

    Post.all.merge_all
    # This will merge all the posts into the first one.
    # The other posts will be deleted after their comment are reattached
    # to the first post.

== License

This project rocks and uses link:MIT-LICENSE.
