Use SVG badges in README where available
Set up client for use in specs

Use the PETE_DEVELOPER_ID and PETE_SECURITY_KEY environment variables
to set valid API credentials while running the tests to record to the
VCR cassettes.
Create VCR cassette tags to only save on success

Created two tags with special behaviour. If you use a cassette with the
tag :ignore_unsuccessful, any requests which fail (with an HTTP status
code outside the range of 100-399 inclusive), the cassette won't be
recorded. This will avoid recording requests for failing tests.

The other tag is :ignore_bad_security_token. This is useful for the
health check route. If the "securityTokenOK" field is false in the
response, then the cassette once again won't be saved, to avoid caching
a response which will cause the specs to fail.
Avoid persisting sensitive data in VCR cassettes

Scrub any developer IDs and security keys in the VCR cassettes.
