This is a small standalone gem featuring a module ripped out from [axiom](https://github.com/dkubb/axiom).
It allows to declare abstract_type classes and modules in an unobstrusive way.

## Examples
``` ruby
class Foo
include AbstractType
# Declare abstract instance method
abstract_method :bar
# Declare abstract singleton method
abstract_singleton_method :baz
end
Foo.new # raises NotImplementedError: Foo is an abstract type
Foo.baz # raises NotImplementedError: Foo.baz is not implemented
# Subclassing to allow instantiation
class Baz < Foo; end
object = Baz.new
object.bar # raises NotImplementedError: Baz#bar is not implemented
```
