/**
* @brief Creates local temporary directory with contents of given scap-workbench RPM
*
* The reason this class exists is because openscap API is quite limited when
* it comes to input. It will only take file paths.
*
* Intended usage:
* @code{.cpp}
* // Assumes openscap 1.0 API.
* struct xccdf_session* sess = 0;
* {
* RPMOpenHelper helper("some-packaged-scap-content-1.rpm");
* // helper automatically creates a temporary directory, extracts everything
* // to it and stores the paths that can later be used
*
* sess = xccdf_session_new(helper.getInputPath());
*
* if (helper.hasTailoring())
* xccdf_session_set_user_tailoring_file(sess, helper.getTailoringPath());
*
* xccdf_session_load(sess);
* }
*
* // At this point helper goes out of scope and the temporary directory is
* // recursively deleted. However the session has been loaded and can still be used!
* @endcode
