###Creating a Heroku Envornment Variable
Let's say you would like to create an enviornmet varialbe for an S3 bucket. You would write the folling:
$ heorku config:set S3_BUCKET_NAME=your-bucket-name

###Updating/Changing a Heroku Environment Variable
This is actually the same as creating a new environment variable.
$ heorku config:set S3_BUCKET_NAME=updated-bucket-name

###Deleting a Heroku Environment Variable
Lets say I'm no longer using S3. I could delete the S3 bucket variable by doing the following:
$ heroku config:unset S3_BUCKET_NAME
