Facebookads

1. Setup.py is the file which installs facebookads packages. Adding adobjects module to this.

1. The new SDK is an improved SDK version, autogenerated using our Marketing API. Hence there is greater coverage to features provided by our API.
2. The adobjects folder contains separate classes for every ad object and possible CRUD operation on these objects can be based on the presence/absence of api_create, api_get, api_update and api_delete methods.
3. This SDK also contains all the breaking changes for v2.6 API version and is compatible with the manual (legacy) SDK. The legacy branch contains the v2.6 version of the manual SDK. We will continue to maintain it till v2.7 is released.
4. The objects.py file is maintained only for compatibility to existing code, it is advisable to start using the individual files under the adobjects folder directly.
