Overview

This library provides a way to call the functions of the SAP Netweaver RFC SDK, i.e. opening a connection to an ABAP system, calling functions etc., as well as running an RFC service

TODO: Create an error class that wraps the SAP error struct, so it can be raised and the caller can get all the information from there +++
