arango orm with identity pattern

## examples

```python

import typing

from arorm import ListProperty, Field, ObjectProperty, PasswordField, Model, ReferenceId, Reference, ReferenceIdList, ReferenceList, Store, RemoteReferenceList

class UserAttributes(ObjectProperty):

    class Settings(ObjectProperty):

        notifications = Field(default=False)

        html5Notifications = Field(default=False)

    last_update: float = Field(default=0)

    last_login: float = Field(default=0)

    settings = Settings()

    

class User(Model):

    __collection__ = 'users'

    name = Field()

    password = PasswordField(hidden=True)

    email = Field()

    attributes = UserAttributes()

    achievements: typing.List[str] = ListProperty(str)

    books: typing.List['Book'] = RemoteReferenceList('author_id', 'Book')

class Book(Model):

    __collection__ = 'books'

    author_id = ReferenceId()

    author = Reference(author_id, User)

    co_authors_ids = ReferenceIdList()

    co_authors: typing.List[User] = ReferenceList(co_authors_ids, User)

db = dict(host='127.0.01', user='root', password='root', port=8529, driver='arango')

store = Store(db)

store.setup_db()

user = store.create(User) # will create a user on commit

book = store.create(Book) # will create a book on commit

book.author = user

book.co_authors.append(user)

store.query(User).filter(User.name == 'admin').delete() # queued to be executed on commit

store.run_after_commit(lambda: print('did commit'))

store.commit()

user.to_json() # -> will now have _id, _rev

book.to_json() # -> will now have author_id set to same id as user

```
