IgnorePaths is not defined

I just installed the latest version (0.7.0) and receive this error. It is because the IgnorePaths is declared after its usage. 

```
>>> from requestlogs import middleware
Traceback (most recent call last):

    _settings['IGNORE_PATHS'] = IgnorePaths(ignore_paths)
NameError: name 'IgnorePaths' is not defined
