CalDAVEx.Auth (CalDAVEx v0.2.1)

Builds HTTP Authorization headers from auth configuration tuples.

Auth tuples are produced by the helpers on the top-level CalDAVEx module (CalDAVEx.no_auth/0, CalDAVEx.basic_auth/2, CalDAVEx.bearer_auth/1) and stored on CalDAVEx.Config. This module converts those tuples into the header list passed to the underlying HTTP client.
