* DESCRIPTION:
* Curl Client for get/post/put/delete requests through the php curl inteface
*
* For anything more complex use guzzlehttp/http
* https://docs.guzzlephp.org/en/stable/index.html
*
* Requests are guzzleHttp compatible
* Config for setup is guzzleHttp compatible (except the http_errors)
* Any setters and getters are only for this class
