4. process inbound/outgoing messag in chain A

Ethan talk on IBC during HackAtom Seoul. YouTube videos with bookmark where he starts talking:

• Talk about IBC, link plays at 1h:57m
• IBC demo, link plays at 2h:31m

Above demo is based on ezekiiel's cw-ibc-example repo. Ethan setup an cw-ibc-demo repo - which he shows in HackAtom.

The cw-ibc-demo also uses ts-relayer for integration tests. It is explain in the HackAtom demo part. Have a look at these files and folders on the repo:

• ci-scripts folder: start and stop scripts for Osmosis and wasmd
• tests folder: npm package, where for example there is cosmwasm.spec.ts file for testing IBC contract interactions on Osmosis and wasmd chain.

#9 PR is a basic ibc.

It is missing the integration tests to make sure its 100% working, but the unit tests passing so we get what we expect.

[Art3miX]

Should we export the ibc-example to its own repo?

This way we could get feedback about it, and let others use it (as well as bring attention to ark protocol in the dev community)

PR #10 should cover this issue, as far as i can see, this handles everything IBC related, and the template is complete.

We might adjust he template in the future, but this is a working template.

I think this example should just cover all the end points and stuff we can do with ibc, with explained comments on each step, including tests.
