Initial commit.
sendgrid_email_received signal is sent on receiving post request from sendgrid
Cleanup
sendgrid_eventhooks should be at the root of the repository

sendgrid_eventhooks is the reusable app we are writing. There is no
advantage in keeping it nested.
This is a third party app. So we only need an example project to test
this app sendgrid_eventhooks.

So let's call it example instead of apps.
