serverless_helpers 0.3.0

## serverless_helpers

This library isn't *required* for writing Python in the [serverless][sls], but
it does make your life easier by handling things like environment variables for
you.

## Usage

```
import serverless_helpers

# all .env files are loaded into the environment
serverless_helpers.load_envs(__file__)

# Loads stack outputs into environment variables as `SERVERLESS_CF_[output name]`
serverless_helpers.load_cfn_outputs()

import os
os.getenv('SERVERLESS_STAGE') # dev

# get role ARN from default serverless CloudFormation stack
os.getenv('SERVERLESS_CF_IamRoleArnLambda') # arn:aws:iam::123456789012:....

# alternate way to read roles
outputs = serverless_helpers.load_cfn_outputs()
outputs['IamRoleArnLambda'] # arn:aws:iam::123456789012:....
```
