== Usage
 
  require 'rubygems'
  require 'module-import'
 
  module Foo
    def foo; 'foo' end
    def bar; 'bar' end
  end
 
  class Importer
    import Foo, :bar
  end
  Importer.new.bar # => 'bar'
  Importer.new.foo # => # NoMethodError
 
  class Importer
    import Foo, :not_defined # => #not_defined not found in Foo (ImportError)
  end
 
 
Giving no methods (or all methods) should behave the same as a normal include
 
  class Importer2
    import Foo # same as import Foo, :foo, :bar
  end
  Importer2.new.bar # => 'bar'
  Importer2.new.foo # => 'foo'
 
However, there is one important difference.  New changes in the included module will not effect the class.
  module Foo
    undef_method :foo
    def bar; fail end
  end
  Importer2.new.bar # => 'bar'
  Importer2.new.foo # => 'foo'
 
== WARNING!
There is no way for Kernel#import to track dependencies between methods!  To help with this, by default, all private methods from the module will be imported unless the option :import_private is set to false
To write a module that works with this system well, your public methods should depend only on private methods.
To use this on someone else's module, you should either import the full module or write tests or inspect the source code of the module you are importing.

== Notes
=== Testing
4:1 test:code ratio, I think I have all the corner cases covered.  In particular, this does not break inheritance and everything works the same for importing into a module as it does for importing into class.
 
=== Implementation
Includes a duplicate of the module that has methods removed
