(Refactor) Mobx state management

[fvictorio]

This is a continuation of #304, with the merge conflicts resolved. I created a new PR because I can't push to @15chrjef repo.

@fvictorio @fernandomg
2.

3. Contributors amount is not empty here: https://wizard.oracles.org/crowdsale?addr=0xa3f54827dE7AC856762F77A0A9701548170e07D6&networkID=1
   But from this branch amount of contributors is 0.

[vbaranov]

Looks good for me now

[igorbarinov]

@fvictorio @fernandomg great job.

• I think we should add a document to Wiki with the state structure and how-to for new developers
• let's start release policy with this important and large PR. How do you feel about release 0.1?

[fvictorio]

0.1 sounds good.

I'll add some documentation in the wiki for new developers, but I don't think documenting the state structure is worth it: it's going to get old fast, and the MobX stores seem pretty self-documenting. What do you think?

[igorbarinov]

If you can document basic ideas of our state to new developers it would be great
I agree with you about state structure if it will be old soon

[vbaranov]

I agree with documenting of the structure. Day will come, when we'll forgot, where some properties for wizard are stored, if we won't describe it.

[fvictorio]

I added a page to the wiki: https://github.com/oraclesorg/ico-wizard/wiki/Source-code-structure

I didn't describe all stores because I think some of them should be replaced with local state.

[igorbarinov]

@fvictorio could we deploy it on stage server? At the moment the way we did it is to merge a PR into stage branch?

Do you have any other ideas for staging?

[fvictorio]

No, that sounds perfect. I'll merge it on the stage branch.

[fvictorio]

Done, it is in the stage server now. I am testing it there.

[igorbarinov]

@fvictorio thank you, will test too

@vbaranov Viktor, btw what was the idea behind syncing to branches using PRs? E.g. #368
If there is no special reason let's sync branches without PRs.

[fvictorio]

It seems to be working fine. I tested crowdsales with token reservation, multiple tiers, whitelisting.

[fvictorio]

Hi, what's the next step here? Do we leave it in stage some time more for testing or can we merge it into master?

[igorbarinov]

Tested basic scenario on the staging server and it worked fine

[igorbarinov]

Congrats everyone on PR merge!

@fvictorio could you please create a tag and release the source code in it with brief description of MobX changes.

[fvictorio]

Sure!
