Add a simple example to the root module

[DevQps]

Description

Currently, there is no example given in the root module which makes it very hard to figure out how to actually use this library. It seems very feature-rich so I am sure many people would be glad to use it if they get some directions on how they should approach it!

If I can be of any help during this process please let me know! I am not very sure on how to use this crate yet but maybe I am able to figure it out with a few hints :)

Some examples that come to my mind:

• Downloading / syncing ROA's with TALs (not sure if this is outside the scope of this crate?)
• Matching against all ROA's.

You are correct that documentation is rather lacking. I am improving it here and there, but indeed there must be better top-level documentation.

That said, the crate is intended to be rather low-level. It contains the functionality that is shared between Routinator and Krill (i.e., the relying party and CA software, respectively). It really only provides the building blocks to start something useful from. Your examples, which rely on having a local copy of the RPKI repository available, are probably better achieved by using Routinator as a library crate – with the caveat that its documentation is in an even worse state.

@partim Thanks for your response! I will go check that out then :) If there's anything I can do to help, please let me know.
