Please mention the following:
- What command was run? python cloudmapper.py report --account my_account
- Are you working out of a virtualenv environment, Docker, or something else? virtualenv, Linux

I did get a number of errors during collect: s3.get_bucket_*({'Bucket': 'bucket-name'}): An error occurred (AccessDenied) when calling the GetBucket* operation: Access Denied

```
$ python cloudmapper.py report --account my_account
* Getting resource counts

wrapping a try/except around it got around this error:
